227	Azo compounds	GB7906756	1979-02-26	GB2035352A	1980-06-18
Novel azo compounds of the general formula:- (E)n@(A)n@ - (R1)n@ - N = N - BAL where A is a charged group which may be positively or negatively charged, E is a counter ion which carries a charge of opposite sign to that carried by A, BAL represents a ballasting group attached to the azo group via an aromatic or heterocyclic ring which may be further substituted, and R1 is an optionally substituted aromatic or heterocyclic group, and n1 is 1 or 2, n2 is 1 or 2 and n3 is 0 or 1 are used in diffusion transfer colour photographic materials. Example: A dyestuff of the formula:-
228	Anthraquinone-azo compounds, their preparation and their use as dyestuffs	GB7931973	1979-09-14	GB2032941A	1980-05-14
The invention provides water- soluble anthraquinone-azo dyestuffs of the general formula in which R1 represents a hydrogen atom or a sulphonic acid group, and the two R1s are not both hydrogen, K represents the radical of a coupling component and Z represents a fibre- reactive group which is linked to a carbocyclic aromatic nucleus of the coupling component, n being 1 or 2. The compounds may also be in the form of their salts. The compounds, preferably in the form of alkali metal salts, are useful for dyeing and printing fibre materials containing carboxamide groups, e.g. silk, wool and other animal hairs, polyamide and polyurethane fibres, and fibre materials containing hydroxy groups, e.g. cotton, linen and viscose rayon. Green to olive-green, blue and grey dyeings are obtained having good fastness to wet processing and very good fastness to light. The invention also provides intermediates for these dyestuffs in which the Zn group is replaced by an NHR group in which R represents a hydrogen atom or a lower alkyl group or a cyano-lower alkyl group.
