ABSTRACT:
Disclosed in a color photograph containing a storability-improving compound capable of forming a chemical bond with an aromatic amine series color developing agent that remains in a photographic material after having been processed for color development to give a chemically inactive and substantially colorless compound in at least one photographic layer on a support. Also disclosed is a method for preparation of color photographs wherein a photographic material containing a silver halide emulsion layer and a color image-forming coupler capable of forming a dye by an oxidation-coupling reaction with an aromatic amine series color developing agent, as coated on a support, is imagewise exposed to light and then subjected to photographic processing, comprising carrying out the photographic processing in the presence of the afore described storability-improving compound. By the use of the storability-improving compound, the color images formed on the color photographs do not fade when stored for long periods of time.
