摘要:
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 R1-radicals and R2-radicals are preferably methyl; and wherein the compounds of formula (II) are preferably (III) R3 is a radical —CH(CH3)—X—D, wherein X is phenylene. D is a group (IV) or a group —C(O)—C1–C18alkyl or a group —O—CH2—CH(OH)—CH2—NR12R13, with R12 and R13 being C1–C18alkyl or together form a 4 to 8 membered ring as defined in claim 1, or D is a group —O—CH2—CH(OH)—CH2—N(R12)—CH2—CHOH—CH2—O—or —O—CH2—CH(OH)—CH2—W—CH2—CHOH—CH2—O— with W being a divalent amino group (—N(C1–C18alkyl)−), a polyamine residue, a polyethyleneimine residue or a polyoxyalkyleneamine residue; Z and Z′ are for example C1–C12alkyl, C3–C12alkenyl, C3–C12alkenyl, C5–C8cycloalkyl, or Z and Z′ together bivalent groups such as —CH2—CH2— or —CH2—C(R18)(R19)—CH(R20)—
