A colour-photographic material which contains, in at least one layer, a compound of the formula (I) <IMAGE> in which X is -NH-, -NR- or -O-, R is alkyl, cycloalkyl or aryl, R1 is a chemical bond or a divalent bridging member (bridge), R2 and R3 are alkyl, alkoxy, alkenyl, cycloalkyl, aryl or aryloxy, or two radicals R2 and R3 are the remaining atoms of a benzene ring fused to the phenyl radical, m and n are from 0 to 3, where all alkyl, alkoxy, cycloalkyl, alkenyl, aryl and aryloxy radicals may be further substituted and one radical R1, R2 or R3 in each of the two phenyl radicals is in the para-position to the oxygen atom, are distinguished by improved dye stability after processing. |
