| The present invention relates to compounds of formula (I): wherein R1 is a dye, and L', R2 and R3 are as defined herein. The compounds of the invention reversibly convert from a hydrophobic form to a hydrophilic form upon contact with water and carbon dioxide. The present invention also relates to methods of dyeing fibres, and methods of decolouring dyed fibres. The method is particularly useful for dyeing polyester fibres. | ||||||

| Improvement in a process for producing an arylazo-aminonaphtholsulfonic acid represented by a free acid of the formula, ##STR1## wherein A is a phenyl or naphthyl group unsubstituted or substituted by one to four members selected from alkyl, alkoxy, phenoxy, sulfonic acid, carboxylic acid, arylamino, amino, nitro and hydroxyl groups and halogen atoms, and m is 0 or 1, which comprises reacting an aminonaphtholsulfonic acid represented by a free acid of the formula, ##STR2## wherein m is as defined above, with a dibasic acid anhydride to obtain an acylaminonaphtholsulfonic acid, coupling a diazonium compound of amine of the formula,A'--NH.sub.2wherein A' is a phenyl or naphthyl group unsubstituted or substituted by one to four members selected from alkyl, alkoxy, phenoxy, sulfonic acid, carboxylic acid, arylamino, acrylamino, nitro and hydroxyl groups and halogen atoms, with the acylaminonaphtholsulfonic acid, and then subjecting the resulting coupling product to hydrolysis in the presence of an acid or an alkali. The arylazo-aminonaphtholsulfonic acid is useful as acid dyes or acid mordant dyes in itself as well as an important intermediate for the production of reactive dyes or direct dyes. | ||||||

| Novel diazonium compounds and methods for their preparation are disclosed. Specifically, 1-(4'-diazoniumphenyl)-1,2-dihydro pyrid-2-imino-sulfinate is prepared by rearrangement of 2-(4'-diazobenzene-sulfonylamino)-pyridine, and 1-(4'-diazoniumphenyl)-2-amino-pyridinium salts are obtained by reaction of 1-(4'-diazoniumphenyl)-1,2-dihydro-pyrid-2-imino-sulfinate with aqueous acids. The novel compounds are useful as precursors for azo dyestuffs. | ||||||
