Abstract

Abstract A silver halide color photographic light-sensitive material is described comprising a support and at least one light-sensitive silver halide emulsion layer having a coupler incorporated therein and at least one light-insensitive hydrophilic colloidal layer, whereby color mixing and color stain (color fog) phenomena are prevented from occurring at the time of color development, said light-insensitive hydrophilic colloidal layer(s) containing a polymer having a repeating unit represented by formula (I) ##STR1## wherein R represents a hydrogen atom, an alkyl group containing from 1 to 6 carbon atoms, or a halogen atom; M represents a hydrogen atom, an alkali metal atom, an alkaline earth metal atom, or an organic base group; X represents an alkyl group containing from 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, an alkylamino group having 1 to 6 carbon atoms, or a halogen atom; m represents 0, 1 or 2; and n represents 1 or 2.
