Color photographic material, useful e.g. for film or paper, contains ester or amide of branched beta-hydroxy-carboxylic acid, e.g. citric acid, as oil former in red-sensitized silver chloride-rich emulsion containing cyan coupler

摘要

Color photographic material with red-sensitized silver halide (AgX) layer(s) rich in silver chloride (AgCl) contains cyan coupler(s) and ester or amide compound(s) (I) of branched beta -hydroxy-carboxylic acids. Color photographic material with red-sensitized silver halide (Ag) layer(s) rich in silver chloride (AgCl) contains cyan coupler(s) and ester or amide compound(s) of branched beta -hydroxy-carboxylic acids of formula (I). R<1> = alk(en)yl, aryl or heterocyclyl; R<2>, R<3> = alk(en)yl, aryl, heterocyclyl or acyl; X<1> = oxygen (-O-) or imino (-NR<4>-); and R<4> = hydrogen (H), alkyl or aryl.
