Abstract

1356176 Photographic silver halide emulsion containing a coloured coupler AGFA-GEVAERT A G 4 May 1972 [7 May 1971] 20745/72 Heading G2C [Also in Division C4] A colour photographic material has at least one silver halide emulsion layer containing a red cyan coupler of the formula:- wherein R 1 , R 2 , R 3 are each H or 1-18C alkyl, at least one being 12-18C alkyl which renders the coupler resistant to diffusion; and R 4 is 4-7C alkyl or cycloalkyl which cycloalkyl group may be substituted. The red cyan coupler may be used in addition to colourless cyan couplers in a photographic silver halide emulsion (see Ex.2).
