PURPOSE:To inhibit generation of rereversal negative image even when a color photographic sensitive material is preserved at high temp. and high humidity for a long time by incorporating at least one kind of specified compd. CONSTITUTION:The title direct positive type color photographic sensitive material is constituted of at least one photographic emulsion layer contg. previously uncoupled internal latent image type silver halide particles and a color picture image forming coupler which is non-diffusive in itself and forms or liberates a dye by oxidation coupling with a color developing agent. Also at least a kind of compd. expressed by formula I is contained. In formula I, each R<1> and R<2> is alkyl group; R<3> is H atom., alkyl group, etc.; each Z<1> and Z<2> is an atomic group necessary for forming a naphthalene ring; X<-> is an anion; n is a number necessary for neutralizing the electric charge of the whole part of a molecule. By this constitution, a photosensitive material prevented remarkably from generation of rereversal negative image is obtd. The effect is particularly distinct when the material is preserved at high temp. and in high humidity for a long time. |
