Process for developing light-sensitive silver halide photographic materials

Claim 1

A process for developing an image-wise exposed light-sensitive silver halide photographic material with a developing solution containing an aldehyde hardening agent in the presence of one or more of compounds having the following formula: ##STR3## in which R 1 represents a substituted carbamoyl group, a cyano group, a nitrogen-containing 5-10 membered heterocyclic group, --COOM or --COOR; each of R 2 and R 3 represents hydrogen, an alkyl group, a substituted or unsubstituted carbamoyl group, a cyano group, --COOM or --COOR; each of R 4 and R 5 represents hydrogen or an alkyl group; and R 6 represents hydrogen or --COOM; wherein M represents hydrogen, an alkali metal or ammonium ion, R represents a lower alkyl or aryl group; X represents a chlorine ion; and each of m and n is 0 or 1, and when M represents an alkali metal or ammonium ion, n is 0, said compound being present in the photographic material or in the developing solution.
