Color photographic silver halide material, useful e.g. as color negative or reversal film or color photographic paper, contains coupler and oxidative developer linked by covalent bridge, preferably hydrazine bridge

摘要

Color photographic material has a base, light-sensitive silver halide emulsion layer(s) and a coupler (I), which has an oxidative developer part and color coupler residue linked by a bridge. Color photographic material has a base, light-sensitive silver halide emulsion layer(s) and a coupler of formula E-L-K (I), which has an oxidative developer part and color coupler residue linked by a bridge. E = oxidative developer part; L = bridging group; K = color coupler residue.
