Abstract

A color photographic silver halide material containing gelatine, comprising a support and at least one photosensitive silver halide emulsion layer and at least one non-photosensitive layer, which material contains at least one compound of the formula (I) or (II) and is hardened with a vinylsulfonyl compound in which R1, R2, R3, m and n have the meanings stated in the description and wherein two residues R2 or R3 may in each case mean a fused carbo- or heterocyclic ring or the compound of the formula I is attached to a polymer chain via one of the residues R1, R2 or R3, in which R11, R12, R13, R14, o and p have the meanings stated in the description wherein two residues R13 or R14 may in each case mean a fused carbo- or heterocyclic ring or the compound of the formula II is attached to a polymer chain via a residue R13 or R14, is distinguished by improved storage stability.
