Abstract

1,159,357. Colour couplers for silver halide materials. AGFA-GEVAERT A.G. Nov.27, 1967 [Nov. 28, 1966], No.53778/67. Heading G2C. [Also in Division C2] A photographic silver halide material contains in the emulsion layer or in a layer in waterpermeable relationship therewith a yellow colour coupler of the formula:- wherein R 1 is H or alkyl, R 2 is alkyl (1-18C), R 3 is alkoxy, aryloxy, alkylmercapto or t-amino, R 4 is H 1 alkyl or alkoxy (1-18C), halogen, aryloxy or alkylmercapto, R 5 is a substituted or unsubstituted phenyl or naphthyl radical and X is, CO or SO 2 . The emulsion may contain a stabilizer 4-hydroxy-6-methyl-1, 3, 3a, 7-tetraazaindene and a chromium acetate hardner.
