Abstract
The light-sensitive color photographic silver halide recording material contains in at least one of its light-sensitive gelatine-containing layer, color formers for the formation of the image dyes in the three primary colors, a crosslinking agent activating the carboxyl groups of gelatine selected from carbamoylonium salts, carbamoylpyridinium salts and carbamoyloxypyridinium salts and a compound acting as aldehyde-scavenger which corresponds to the general formula ##STR1## wherein Z represents the atoms required for completing a 5-6-membered substituted or unsubstituted carbocyclic ring or a substituted or unsubstituted heterocyclic ring which may contain oxygen, nitrogen or sulfur as hetero-atom.
Claims5
Light-sensitive color photographic silver halide recording material consisting of a layer support and applied to this layer at least one light-sensitive gelatine-containing layer containing color couplers for the formation of the image dyes in the three primary colors, a cross-linking agent which activates the carboxyl groups of the gelatine and a compound acting as aldehyde-scavenger, characterised in that the cross-linking agent which activates the carboxyl groups of gelatine is a gelatine hardener selected from carbamoylonium salts, carbamoylpridinium salts and carbamoyloxypyridinium salts, and the compound acting as aldehyde-scavenger corresponds to the following general formula:
- ##STR68## wherein Z represents the atoms required for completing a 5- or 6-membered, substituted or unsubstituted carbocyclic ring or a substituted or unsubstituted heterocyclic ring which may contain oxygen, nitrogen or sulfur as heteroatom.
