PHOTOGRAPHIC SILVER HALIDE MATERIAL CONTAINING AS HARDENER THE REACTION PRODUCT OF A VINYL SULPHONYL COMPOUND AND AN AMINE

摘要

A photographic silver halide material At least one gelatin-containing layer of a photographic silver halide material is hardened with a reaction product of two compounds corresponding to the formulae (A) R(SO2-CH=CH2)n in which R is an n-functional aliphatic, aromatic, cycloalkyl or heterocyclic group and n is an integer of from 3 to 6 and (B) in which R1 and R2 may be the same or different and represent hydrogen or a lower alkyl group, R3 is an alkyl group, an aminoalkyl group a substituated or unsubstituated aromatic group, a substituated or unsubstituated 5- or 6-membered heterocyclic ring which may be attached to the N-atom of (B) either directly or through a carbon-containing group, or R2 and R3 together represent the atoms required to complete a heterocyclic ring system.
