Abstract
Abstract A silver halide color photographic light sensitive material comprising a support which is both side coated with a polyolefin resin is disclosed. A hydrophilic colloidal layer containing a white pigment and a silver halide emulsion layer are provided on the support and the silver halide emulsion layer contains at least one of the compounds represented by the following Formula I, ##STR1## wherein R 1 represents an alkyl group, a cycloalkyl group or an aryl group; R 2 represents a fluorine atom, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, a dialkylamino group, an alkylthio group or an arylthio group; R 3 represents a group substitutable to a benzene ring; n is an integer of 0 or 1; Z represents a hydrogen atom or a group capable of splitting off when coupling it to the oxidized product of a developing agent; and Y represents a monovalent organic group including a ballast group.
