Abstract

The invention comprises dyes of formula <FORM:0898706/IV (c)/1> where Ar is an aryl nucleus, Z is OH, Hlg, Alk or AlkO, m 0 or 1, n 0 or 1-4, q 1 or 2, R alkylene, Y o- or p-dihydroxyphenyl or an alkyl or halogen substituted derivative thereof and Xa and Xb are coupling component residues. The dyes are made by conventional diazotization and coupling processes and the hydroxy groups in Y may be protected during these processes by using, e.g. in the form of o-acetyl derivatives. Benzene and naphthalene nuclei are indicated for Ar. Preferred alkyl and alkoxy groups for Z are those containing 1-5 carbon atoms. Preferred dyes are those in which Ar is a benzene residue and where R is an ethylene group. Representative of indicated coupling components are phenol, anilines, naphthols, anthrols, naphthylamines, pyrazolones, pyrroles, 1,3-diketones and beta-ketonic acid arylamides. The coupling components may contain substituents such as alkyl, sulpho, alkoxy, aryl, aryloxy, amino, keto, alkylamino, arylamino, hydroxy, cyano, alkylamido, arylamido, carbalkoxy, carboxamido and sulphonamido groups. Preferred diazo components are 2 - [gamma - (21, 51 - dimethoxy - 31 - aminophenyl) - propionyl and beta - methyl - propionyl - ] - and 2 - (gamma - [21, 51 - di - methoxy - 31 - (211, 511 - dimethoxy 311 - amino - phenylazo) - phenyl] - propionyl) - hydroquinones. Amongst coupling components indicated or specified are 4-methyl, methoxy- and benzyl-1-naphthols, 4-methoxy- and -aectamido-a -naphthylamines, 1,5-naphtholenediamine, 1-hydroxy-2-naphthanilide, phenol, p-cresol, aniline, 2,5-dimethoxyaniline, 1-hydroxyanthracene, diketohydrindene, malonitrile, acetoacetanilide and 1-phenyl - 3 - methyl - 5 - pyrazolone. Indicated coupling components for use in compounds where p is Z are 1,6-dihydroxynaphthalene and 1-naphthol. A further indicated value for R is isopropylene. The dyes are developers and are of particular use in colour photography. Examples are provided of the preparation of the dyes and thie use in photographic processes and compositions. Specifications 804,971, 804,972, 811,579, 853,478, 853,479 and 898,707 are referred to.
