    • PURPOSE:To improve the fastness of a color image to light, heat and humidity and to suppress generation of colored stains upon lapse of time after a color development processing by combining a specific compd. and org. synthetic high polymer. CONSTITUTION:This photosensitive material contains at least one kind of the org. synthetic high polymer added as an emulsified dispersion and at least one kind of the compd. which forms a chemically inert and substantially colorless compd. by chemically bonding the arom. amine developing agent remaining after the color development processing or the oxidant thereof in a photographic layer. The org. synthetic high polymer to be used may be the high polymer of any polymer if the polymer is insoluble in water and is soluble in an org. solvent. The ratio to be occupied by the compd. is 1X10 -10mol., more preferably 3X10 -5mol. per 1mol. of the coupler. The color fading and dark color fading are thereby improved with good balance and particularly the excellent image preservable property is exhibited at and under a high temp. and high humidity; in addition, the colored stains to be generated upon lapse of time after the processing are prevented.

    • PURPOSE:To obtain a color image which has excellent image stability and wet heat fastness and is prevented of a pink stain by providing a silver halide photographic emulsion layer contg. the dispersion of fine lipophilic particles obtd. by emulsifying and dispersing a soln. mixture composed of a specific oil soluble coupler and non-color formable oil soluble polymer. CONSTITUTION:This photosensitive material has the silver halide photographic emulsion layer contg. the dispersion of the fine lipophilic particles obtd. by emulsifying and dispersing the soln. mixture contg. the oil soluble coupler which is capable of forming a dye by coupling with the oxidant of an arom. primary amine developing agent and is expressed by the formula I and the non-color formable oil soluble polymer on a base. In the formula I, Q1 denotes an atomic group necessary for forming nitrogenous heterocycles of >=5-membered rings together with a carbon atom; Z1 denotes a hydrogen atom, a group which can be eliminated in coupling reaction with the oxidant of a color developing agent; R1 denotes an acyl group, sulfonyl group; R2 denotes a hydrogen atom, aliphat. group of 1-8C. The photosensitive material having the excellent image stability and wet heat fastness is thereby obtd. and the generation of the pink stain is prevented.

    • PURPOSE:To improve the discoloration of pigment images formed from each couplers due to a light by providing the nonphotosensitive layer of an emulsion contg. a specified U.V. absorber at a far position and/or a near position separated from a supporting body, seeing from a photosensitive silver halide emulsion layer which exists at the most far position from the supporting body, on the supporting body. CONSTITUTION:The titled material provides the nonphotosensitive layer contg. the dispersion at the prescribed side of the supporting body, and said dispersion is obtd. by emulsifying the solution contg. a mixture of at least one kind of the U.V. absorber selected from the compds. shown by formulas I and II, and at least one kind of a homopolymer or a copolymer which is insoluble in water and soluble in an org. solvent, and has a repeating unit shown by formula III in a main or a side chain of the polymer. In the formulas I and II, R1-R3 are each hydrogen or halogen atom., etc., R4 and R5 are each hydrogen atom. or alkyl group, etc., X is -CO- or -COO- group, (l), (m) and (n) are each a positive integer of 1-4. Thus, the excellent photographic sensitive material having the improved photodurability of a pigment image is obtd.
