ABSTRACT:
Light-sensitive silver halide photographic elements are disclosed comprising a support and silver halide emulsion layer or layers, wherein at least one of said silver halide emulsion layers contains tabular silver halide grains having an average diameter:thickness ratio of at least 3:1 and highly deionized gelatin hardened with a compound of formula (CH.sub.2 .dbd.CH--SO.sub.2 --).sub.n --A, wherein A is an n-valent organic group containing at least one hydroxy group and n is 2,3 or 4.
The light-sensitive materials can be advantageously used in high temperature processing in automatic processors which include transporting rollers and have good characteristics of resistance to pressure marking.
