说明书全文	This is a division of application Ser. No. 551,653 filed Feb. 21, 1975 U.S. Pat. No. 4,008,999. The present invention relates to diphenylamines or N-alkyl leuco indoanilines disubstituted in the 4' position, to their preparation and to their use for dyeing keratinic fibers, and in particular living human hair. A currently utilized technique for dyeing keratinic fibers, and especially living human hair, comprises applying to the hair, in the presence of an oxidizing agent added at the moment of use (generally hydrogen peroxide), a dye composition comprising a mixture in an appropriate cosmetic support, of compounds belonging to one or the other of the two following classes. The first class of compounds, generally called "oxidation bases" is principally constituted by paraphenylenediamines or paraaminophenols which, on oxidation, produce para benzoquinonediimines or parabenzoquinonemonoimines. The second class of compounds, generally called "couplers" include, especially, metaaminophenols, metaacetylaminophenols, metadiamines and metadiphenols. They are compounds, with which when the benzoquinone mono- or di-imines, will react to produce dyes called, depending upon their structure, indophenols, indoanilines or indamines. These dyes, which provide a range of shades of exceptional richness, are primarily characterized by the luminosity and the richness in glints of dyeings or colorations they impart to the fibers dyed therewith. However, when a complex dye composition is employed, i.e. a composition which includes several bases and several couplers, it is very difficult to foresee in the final shade the contribution of each possible couple of oxidation base and coupler. In other words, on the one hand, it is very difficult at the outset to predict with any exactitude the final shade that will be attained and, on the other hand, for a given dye composition, it is not often easy to be assured of a perfectly reproducible result. These difficulties are increased by the fact that different secondary reactions can modify the final shade, such secondary reactions including, for instance, formation of Bandrowsky base type compounds from the with oxidation bases; recondensation of a molecule of an oxidation base on certain indophenols or on certain indoanilines or indamines; and formation of quinones and the like. Heretofore, it has also been proposed to use in the dyeing of hair, some indoanilines which are well defined compounds and which impart to the hair essentially perfectly reproducible shades. However, some inconvenience has been experienced in the use of these compounds since they possess only a slight affinity for keratinic fibers under conventional conditions for dyeing hair. The present invention relates to leuco derivatives of indoanilines which are colorless compounds and which, when applied in an aqueous solution to fibers to be dyed, are oxidized at the interior of the keratinic fibers so as to give the corresponding indoanilines. These resulting indoanilines are the colored compounds which are directly responsible for the dyeing of the fibers. The colorations thus obtained exhibit fastness and intensity of coloration which are greater than those of dyeings effected by the direct application of indoanilines, because of the enhanced solubility and better keratinic fiber penetration characteristics of the compounds of the present invention. The oxidation of leuco derivatives of the present invention to indoanilines can be effected by the oxygen in air or by the use of an oxidizing agent incorporated into the dye composition at the moment of use. Representative oxidizing agents include hydrogen peroxide, urea peroxide and ammonium persulfate. While the use of the leuco derivatives of indoanilines for dyeing hair has already been proposed, the present invention enlarges the family of such leuco derivatives. Thus the leuco derivatives of indoanilines or diphenylamines of the present invention have the formula ##STR2## wherein R₁ and R₄ each independently represent a member selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, amino, lower alkyl amino, acylamino, lower carbamylalkyl amino, lower hydroxyalkyl amino, lower carbalkoxy amino and ureido; R₂ and R₃ each independently represent a member selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, acylamino and ureido; R₅ and R₈ each independently represent a member selected from the group consisting of halogen, lower alkyl and lower alkoxy; and R₆ and R₇ represent lower alkyl with the proviso that (a) when both R₆ and R₇ represent methyl, (1) one of R₁ and R₄ must represent a member selected from the group consisting of amino, lower alkyl amino, lower carbamylalkyl amino, lower hydroxyalkyl amino and ureido, or (2) one of R₁ and R₄ represent acylamino and R₂ and R₃ are not both hydrogen; and (b) that when both R₆ and R₇ represent ethyl, R₂ and R₃ are other than tertiobutyl. The terms lower alkyl and lower alkoxy mean alkyl and alkoxy containing 1-6 carbon atoms, preferably 1-4 carbon atoms. The presence of alkyl substituents as R₆ and R₇ results in shifting the colors obtained towards the blues. The present invention also relates to diphenylamines of formula (I) in the form of their salts such as, for instance, the hydrochlorides, hydrobromides, sulfates and phosphates thereof. The diphenylamines of formula (I) are the leuco derivatives of indoanilines of formula (II) ##STR3## wherein R₁, R₂, R₃, R₄, R₅, R₆, R₇ and R₈ have the meanings given above. The indoanilines of formula (II) can be prepared by the condensation of a substituted aniline of formula (III) ##STR4## wherein Z represents NO or NH₂ and R₅, R₆, R₇ and R₈ have the meanings given above, or a salt thereof, on a phenolic compound of the formula (IV) ##STR5## wherein R₁, R₂, R₃ and R₄ have the meanings given above, or a salt thereof. When Z represents --NH₂, the condensation is carried out in an aqueous, hydroalcoholic or hydroacetonic medium, at an alkaline pH generally greater than 8, in the presence of an oxidizing agent such as, for example, ammonium persulfate, potassium ferricyanide and hydrogen peroxide and at a temperature ranging generally between about 0° to 25° C. The alkaline pH is obtained by the addition to the reaction medium of ammonia or an alkaline carbonate such as sodium carbonate. The molar ratio of substituted phenol to substituted aniline can range between about 1:0.5 to 1:1.2 and is, preferably about 1:1. The molar ratio of oxidizing agent to substituted phenol ranges from about 1:1 to 4:1 and is preferably between about 1:1 and 2:1 when ammonium persulfate is employed as the oxidizing agent. This molar ratio is about 8:1 when hydrogen peroxide is employed as the oxidizing agent. Hydrogen peroxide is usually used in the form of a 6 weight percent solution thereof. The reaction medium can be water, a lower alkanol which preferably is ethanol, propanol or isopropanol, an acetone-water mixture or a lower alkanol-water mixture wherein said mixtures the ratio of acetone or alkanol to water ranges between about b 1:3 to 2:1. When Z represents --NO the condensation is generally carried out at a temperature ranging between about 30° to 60° C., preferably 40° to 55° C., in an ethanol-water mixture, preferably a 1:1 mixture thereof, which is either neutral or has been made alkaline by the addition thereto of a dilute solution of sodium hydroxide. The condensation is carried out in the absence of an oxidizing agent. The reduction of the indoanilines (benzoquinoneimines) of Formula II is carried out using an alkaline hydrosulfite, preferably sodium hydrosulfite, in the presence of sodium hydroxide or acetic acid. Alternatively the reduction can be effected using an alkaline sulfide, preferably ammonium sulfide or by catalytic hydrogenation in the presence of a palladium on charcoal catalyst. According to a first advantageous method of reducing the indoanilines, excess sodium hydrosulfite is dissolved in an aqueous solution of 1 N NaOH. To the resulting solution there is added, over a period of about 15 to 30 minutes, while stirring the mixture and maintaining the temperature thereof between about 0° to 30° C., the benzoquinoneimine in solution or suspension in ethanol. Agitation of the resulting mixture is continued until the solution becomes colorless which generally requires between about 15-60 minutes. The desired diphenylamine (leuco indoaniline) is precipitated by cooling the reaction mixture to 0° C. For certain diphenylamines it is, moreover, necessary to acidify the solution, for example by the addition thereto of acetic acid (see Examples 4, 5, 9, 10, 11, 13 and 14 infra) or of carbonic gas (see Example 12 infra). Cooling to 0° C. is effected with the use of ice or solid carbon dioxide, the latter serving both to cool the reaction mixture and to acidify the same (see Examples 7, 8 and 15 infra). According to a second method of reducing the benzoquinoneimines, the benzoquinoneimine is dissolved in ethanol (95° titer). To the resulting solution there is added, at ambient temperature, a solution of ammonia saturated with hydrogen sulfide. The desired diphenylamine is precipitated by the addition thereto of water (see Example 6, infra). The diphenylamine of Example 3, below, has been prepared in accordance with a third method according to which excess sodium hydrosulfite is dissolved in a 10% aqueous solution of acetic acid. To this solution, maintained at a temperature between about 15°-20° C., there is added, while stirring the same, the benzoquinoneimine in the form of an ethanol solution thereof. Stirring is continued until the solution becomes colorless which is effected in proportion to the addition of the benzoquinoneimine. The solution is then neutralized with ammonia to the point of the precipitation of the diphenylamine in crystalline form which precipitation occurs at a pH of about 5 to 7.5. According to a fourth method of reducing the benzoquinoneimines, as seen for instance in Examples 1 and 2 below, 0.004 mole of benzoquinoneimine is partially dissolved in 150 ml of absolute ethanol. There is then added thereto 0.2 g of palladium on charcoal (10 weight percent palladium) as a catalyst and the indoaniline is reduced by hydrogenation under atmospheric pressure. The reaction mixture is then filtered to recover the catalyst after which the remaining mixture is concentrated under a vacuum and under a nitrogen atmosphere. The desired diphenylamine is then precipitated in the form of crystals by the addition of ice water or in the form of a salt by the addition of an acid. The diphenylamines of the present invention are usefully employed for dyeing keratinic fibers and, in particular, living human hair. These diphenylamines, when applied to hair in an aqueous or hydroalcoholic solution, at a concentration ranging between about 0.002 to 5 weight percent thereof, and preferably between 0.02 to 3 weight percent, provide, after oxidation, either with air or by another oxidizing agent such as hydrogen peroxide, urea peroxide or ammonium persulfate, a range of shades which are very rich in the area of pinks to violets, blues and greens. Additionally, the diphenylamines of the present invention provide some very luminous grays and beiges which are rich in glints. The present invention also relates to a composition for dyeing keratinic fibers, particularly living human hair, comprising an aqueous solution or hydroalcoholic solution, preferably hydroethanolic or hydroisopropanolic, of at least one diphenylamine of Formula (I) wherein R₁ and R₄ each independently represent a member selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, amino, lower alkyl amino, acylamino, lower carbamylalkyl amino, lower hydroxyalkyl amino, lower carbalkoxy amino and ureido; R₂ and R₃ each independently represent a member selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, acylamino and ureido; R₅ and R₈ each independently represent a member selected from the group consisting of hydrogen, halogen, lower alkyl and lower alkoxy; and R₆ and R₇ represent lower alkyl. As indicated above, said lower alkyl and lower alkoxy groups or moieties contain 1-6 and preferably 1-4 carbon atoms. The dye composition of the present invention can also include a salt of the diphenylamines of Formula (I) and in particular the hydrochloride, hydrobromide, sulfate or phosphate thereof. The dye compositions according to the present invention can include as the active dyeing agent only the compounds of formula (I). However, they can also include other known leuco derivatives of indoanilines, indamines or indophenols, or even oxidation dyes such as ortho- or para-phenylenediamines or ortho- or para-aminophenols, as well as benzene compounds trisubstituted or tetrasubstituted by hydroxy, amino or alkoxy groups and couplers such as metadiamines, metadiphenols, metaaminophenols, metaacetylaminophenols or even direct dyes such as nitrobenzene dyes, azo dyes or anthraquinone dyes, indoanilines, indamines and/or indophenols. The compositions according to the present invention are generally provided in the form of an aqueous or hydroalcoholic solution containing one or more compounds of formula (I), in admixture or not with other dyes. They can, however, also include thickening agents and be provided in the form of a cream or gel. Representative thickening agents that can be incorporated into the dye composition of the present invention include cellulose derivatives such as methyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose or acrylic polymers such as the sodium salt of polyacrylic acid or carboxyvinyl polymers. The dye composition can contain as solvents, water, lower alkanols for example ethanol or isopropanol, polyalcohols such as glycols, for example, ethylene glycol, propylene glycol, butyl glycol, diethyleneglycol and the monomethyl ether of diethylene glycol. The dye composition according to the present invention can also include other components generally employed in cosmetics, such as surface active agents used as carriers, as thickening agents, as dispersants or as wetting agents; swelling agents; penetrating agents; emollients; polymers and/or perfumes. The composition of the present invention can also be packaged in aerosol containers together with an aerosol propellant. Representative surface active agents include oxyethylenated alcohols and particularly oxyethylenated lauryl alcohol, partially sulfated oxyethylenated lauryl alcohol and preferably a mixture of 19% partially sulfated lauryl alcohol oxyethylenated with 2 moles of ethylene oxide and 81% of the sodium sulfate salt of this same oxyethylenated alcohol, the alkaline salts or ammonium sulfates of long chain fatty alcohols, for example, ammonium lauryl sulfate, oxyethylenated alkylphenols and preferably nonylphenol oxyethylenated with 4 or 9 moles of ethylene oxide per mole of alkylphenol, oxyethylenated fatty acids and the sulfates and sulfonates of fatty alcohols optionally oxyethylenated. Representative aerosol propellants usefully employed in compositions according to the present invention include nitrogen, nitrous oxide, volatile hydrocarbons such as butane, isobutane or propane, or preferably fluorinated hydrocarbons (sold under the name of Freon by Dupont) such as as dichlorodifluoromethane, 1,1-difluoromethane, 1,2-dichloro-1,1,2,2-tetrafluoro ethane and 1-chloro-1,1-difluoromethane. Mixtures of two or more hydrocarbons or fluorinated hydrocarbons can also be used. The pH of the compositions of the present invention can vary widely and generally it ranges between about 4.5 to 12 and preferably between about 6.5 and 10.5. The pH of the composition can be adjusted with the aid of an alkalizing agent such as, for example, ammonia, mono-, di- or tir-ethanolamine, di- or tri-sodium phosphate, sodium carbonate or potassium carbonate, or with the aid of an acidifying agent such as, for example, acetic acid, lactic acid, phosphoric acid or citric acid. The dyeing of keratinic fibers and, in particular, living human hair, with the use of the dye compositions of the present invention, is carried out in a conventional manner by applying the said composition to the fibers to be dyed, permitting said composition to remain to contact with the fibers for a period of time ranging from about 5 to 30 minutes, rinsing and optionally washing the fibers and then drying the fibers. Prior to applying the said composition to the fibers, there can be added to said composition an oxidizing agent such as 30 to 100 percent by volume of hydrogen peroxide, generally 6% (20 volumes), or 0.1 to 15% by weight of an oxidizing agent such as urea peroxide or ammonium persulfate. The compositions according to the present invention, when present in the form of a hydroalcoholic solution, can also include a cosmetic resin, so as to provide a colored hair setting lotion, which can be applied to wet or moist hair before setting. Representative cosmetic resins that can be used in the hair setting lotion composition of the present invention include such film-forming polymers as polyvinylpyrrolidone; copolymers of polyvinylpyrrolidone and vinyl acetate; copolymers of vinyl acetate and an unsaturated carboxylic acid such as crotonic acid; copolymers resulting from the copolymerization of vinyle acetate, crotonic acid and an acrylic or methacrylic ester; copolymers resulting from the copolymerization of vinyl acetate and a vinyl alkyl ether; copolymers resulting from the copolymerization of vinyl acetate, crotonic acid and a vinyl ester of a long carbon chain acid or even of an allyl or methallyl ester of a long carbon chain acid; copolymers resulting from the copolymerization of an ester derived from an unsaturated alcohol and a short carbon chain acid, of an unsaturated short carbon chain acid and of at least one ester derived from a short carbon chain saturated alcohol and an unsaturated acid; and copolymers resulting from the copoymerization of at least one unsaturated ester and at least one unsaturated acid. Representative preferred cosmetic resins include polyvinylpyrrolidone having a molecular weight ranging between about 10,000 to 360,000; copolymers of 10% crotonic acid and 90% vinyl acetate having a molecular weight ranging between about 10,000 or 70,000; copolymers of vinylpyrrolidone and vinyl actate having a molecular weight ranging between about 30,000 to 200,000 wherein the ratio of VP to VA ranges between 30:70 to 70:30; copolymers of maleic anhydride and methyl vinyl ether in a 1 to 1 molar ratio, having a specific viscosity, measured at 25° C. and at a concentration of 1 g in 100 ml of methylethylketone ranging between about 0.1 and 3.5; the monoethyl, monoisopropyl and monobutyl esters of said maleic anhydride-methyl vinyl ether copolymers; copolymers of maleic anhydride and vinylbutyl ether in a 1 to 1 molar ratio; terpolymers of methyl methacrylate (15-25%) stearyl methacrylate (25-35%) and dimethylaminoethyl methacrylate (52-62%), preferably quaternized for example by dimethyl sulfate, and the viscosity of which, measured at the boiling point of the ether and at a concentration of 5% in dimethylformamide, ranges between about 8-12 centipoises and terpolymers of vinyl acetate (75-85%), allyl stearate (10-20%) and allyloxy acetic acid (3-10%), the viscosity of which, measured at the boiling point of ether and at a concentration of 5% in dimethylformamide ranges between about 4.4 and 5 centipoises. These cosmetic film-forming resins are used generally in an amount between about 1-3 percent by weight of the total hair setting lotion composition. The alcohols generally employed in the production of the hair setting lotion compositions of the present invention are low molecular weight alcohols, preferably ethanol or isopropanol. These alcohols are used in an amount of about 20 to 70 weight percent of the total composition.
