Silver halide photographic material containing a polymer with a photographically useful group which is rendered non-diffusive by cross-linking

Abstract

A silver halide photographic material is described comprising at least one layer which contains at least (1) a polymer comprising as constitutional components thereof a repeating unit having a photographically useful group and at least one repeating unit having a sulfinic acid group or a sulfinate group, and (2) a compound having at least one functional group capable of reacting with at least one of a sulfinic acid group and sulfinate group and at least one functional group capable of reacting with at least one of a sulfinic acid group, a sulfinate group and a primary amino group. Said photographic group-containing polymer (1) may be fixed in a photographic layer according to the present photographic material, and does not substantially migrate therefrom during development or other photographic treatment, thus resulting in formation of color images of high density.
