A colour 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 -H(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-C12alkinyl, C5-C8cycloalkyl, or Z and Z' together bivalent groups such as -CH2-CH2- or -CH2-C(R18)(R19)-CH(R20)-.
