ABSTRACT:
A silver halide color photographic photosensitive material is disclosed which comprises a transparent support on which there are provided at least one cyan color forming coupler containing layer, at least one magenta color forming coupler containing layer, and at least one yellow color forming coupler containing layer, and at least one light-insensitive layer, wherein a compound represented by formula (I), a compound represented by formula (IIa) or (IIb) or both, and an internal latent image forming silver halide grain are contained in the photographic material: ##STR1## wherein Z.sup.11 represents a group of non-metal atoms which is required to form a five or six membered heterocyclic ring, and Z.sup.11 may be substituted with substituent groups; R.sup.11 is an aliphatic group; and R.sup.12 is a hydrogen atom, an aliphatic group or an aromatic group; R.sup.11 and R.sup.12 may be substituted with substituent groups; R.sup.12 may be joined to the heterocyclic ring completed by Z.sup.11 to form a ring; provided that at least one of the groups R.sup.11, R.sup.12 and Z.sup.11 contains an alkyl group, an acyl group, a hydrazine group or a hydrazone group, R.sup.11 and R.sup.12 may be combined to form a dihydropyridinium skeleton; moreover, at least one of the groups R.sup.11, R.sup.12 and Z.sup.11 may have a group which promotes adsorption on silver halide; and Y.sup.11 is a charge balancing counter ion and n is 0 or 1: ##STR2## wherein R.sub.21, R.sub.22 and R.sub.23 each represents an aliphatic group, an aromatic group, or a heterocyclic group; R.sub.25 represents an aniline group or an acylamino group; R.sub.24 represents a substituted phenyl group; X.sup.21 represents a linkage group and X.sup.21 may not exist; R.sub.26 represents a group which can be substituted on a benzene ring; and m represents an integer of 0 to 4.
