Abstract
A color photographic material which contains on a support at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler, at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, together with customary non-light-sensitive layers, characterized in that at least one layer contains a compound of formula (I) or (II) wherein the R-radicals and R-radicals are preferably methyl; and wherein the compounds of formula (II) are preferably (III) Ris a radical —CH(CH)—X—D, wherein X is phenylene. D is a group (IV) or a group —C(O)—C–Calkyl or a group —O—CH—CH(OH)—CH—NRR, with Rand Rbeing C–Calkyl or together form a 4 to 8 membered ring as defined in claim 1, or D is a group —O—CH—CH(OH)—CH—N(R)—CH—CHOH—CH—O—or —O—CH—CH(OH)—CH—W—CH—CHOH—CH—O— with W being a divalent amino group (—N(C–Calkyl)−), a polyamine residue, a polyethyleneimine residue or a polyoxyalkyleneamine residue; Z and Z' are for example C–Calkyl, C–Calkenyl, C–Calkenyl, C–Ccycloalkyl, or Z and Z′ together bivalent groups such as —CH—CH— or —CH—C(R)(R)—CH(R)—
