摘要:
Thermal and photochemical yellowing of a color photographic element, such as a color print, is inhibited by incorporating into the photographic element an ionizable epoxy compound having the formula:
wherein R is H, an alkyl group, or an aryl group; L₁ is an alkyl group or an aryl group; L₂ is -O-, -CO-, -S-, -SO₂-, -PO₂-, -CO₂-, -NHCO- or -NHSO₂-, wherein L₂ may be orientated in either direction; L₃ is an alkyl group; m is 0 or 1; p is 0 or 1; and X is -NHSO₂R', -SO₂NHR', -COOH,
wherein R' is H or an alkyl or aryl group, with the proviso that where L₂ comprises an ionizable group, X may also be an alkyl group or an aryl group.

摘要:
A silver halide photographic light-sensitive material comprises a support and provided thereon, a silver halide emulsion layer containing spectrally sensitized silver halide grains having a silver chloride content of not less than 90 mol%, a cyclic compound having a 9- or more-membered ring containing a hetero atom, and at least one compound represented by the following formula (S):
wherein Q represents an atomic group necessary to form 5- or 6-membered hetero cyclic ring, provided that said Q may form a condensed ring with a benzene ring; and M represents a hydrogen atom, an alkali metal atom, or an ammonium group.

摘要:
A silver halide color photographic material composed of a support having thereon at least one light-sensitive silver halide emulsion layer, at least one layer thereof containing a yellow coupler represented by formula (I), a sparingly water-soluble epoxy compound represented by formula (II) and a water-insoluble but organic solvent-soluble homopolymer or copolymer: wherein R 1 represents an N-arylcarbamoyl group; and Z 1 represents a group capable of being released by a reaction with the oxidation product of an aromatic primary amine color developing agent; and wherein R 1 , R 2 , R 3 and R 4 , which may be the same or different, each represents hydrogen, an aliphatic group, an aromatic group, an aliphatic oxycarbonyl group, an aromatic oxycarbonyl group or a carbamoyl group; provided that at least one of Ri, R 2 , R 3 and R4 represents a group other than hydrogen; R 1 , R 2 , R 3 and R 4 contain a total of 8 to 60 carbon atoms; and R, and R 2 , or R 1 and R 3 may be linked to form a 5- membered to 7-membered ring. Because of the combination of the particular yellow coupler, epoxy resin and polymer, the storage stability of the yellow image formed in the material is excellent.
摘要:
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 whrein 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, comrising 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.
