Abstract

A colour photographic silver halide material which contains in at least one layer at least one compound of the general formula (I) ##STR1## in which R.sub.1 means hydrogen, alkyl or acyl, PA1 R.sub.2, R.sub.3 mutually independently mean alkyl, cycloalkyl, alkenyl, aryl, halogen, OR.sub.4, SR.sub.5, NR.sub.6 R.sub.7, nitro, cyano, SO.sub.2 R.sub.8, COOR.sub.9, COR.sub.10 or hetaryl, PA1 R.sub.4, R.sub.5, R.sub.9 mutually independently mean alkyl, cycloalkyl, alkenyl, aryl or hetaryl, PA1 R.sub.6, R.sub.7 mutually independently mean H, R.sub.4, COR.sub.10, COOR.sub.9, SO.sub.2 R.sub.8, PA1 R.sub.8, R.sub.10 mutually independently mean alkyl, cycloalkyl, alkenyl, aryl, hetaryl or NR.sub.6 R.sub.7, PA1 n, m mean 0, 1, 2, 3 or 4 or two residues R.sub.2 or R.sub.3 may each mean a fused carbo- or heterocyclic ring or the compounds of formula I are linked to a polymer chain via R.sub.1, R.sub.2 or R.sub.3 PA1 is distinguished by elevated storage stability.
