Abstract
A silver halide color photosensitive material is disclosed, which has on a support at least one photosensitive silver halide emulsion layer, wherein at least one nondiffusible compound represented by the following formula (I) is contained to inhibit generation of color stain and color fog and to ensure excellent keeping quality: ##STR1## wherein R.sup.1 represents an aryl group or a heterocyclic group, R.sup.2 represents an alkyl group, a cycloalkyl group, an alkoxy group or an aryloxy group, R.sup.3 represents an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group and X represents an oxygen atom or a sulfur atom; provided that R.sup.3 does not represent a phenyl group when R.sup.2 represents a phenoxy group. ##STR2## wherein R'.sup.1 represents an aryl group or a heterocyclic group; A'.sup.1 and A'.sup.2 each represents a hydrogen atom or a hydrolyzable group; X represents an oxygen atom or a sulfur atom; and Y.sup.1 represents atoms completing a phosphorus-containing heterocyclic ring. ##STR3## wherein R'.sup.1 represents an aryl group or a heterocyclic group; R'.sup.2 represents an alkyl group, a cycloalkyl group, an aryl group, a heterocyclic group, an alkoxy group or an aryloxy group; A'.sup.1 and A'.sup.2 each represent a hydrogen atom or a hydrolyzable group; G represents a carbon atom or a phosphorus atom; X represents an oxygen atom or a sulfur atom; when G represents a carbon atom, m is 2 and n is 0; when G represents a phosphorus atom, m is 2 and n is 1, or m is 3 and n is 0; and two or three R'.sup.1 N(A'.sup.1)N(A'.sup.2)-- groups may be the same or different. A compound represented by the formula (I-1) or (II-1) is also disclosed.
