Abstract: The invention provides a photographic element comprising at least one emulsion layer comprising at least 50 mol% silver chloride, which layer comprises at least one DIR coupler in association with at least one image dye-forming coupler, characterised in that the relative reactivity ratio krel of at least one DIR coupler and an associated image coupler is less than or equal to 1.0, wherein krel = k1/k2; k1 = the second order rate constant for the reaction of DIR coupler with oxidised developer and k2 = the second order rate constant for the reaction of image coupler with oxidised developer. The DIR couplers when associated with image couplers such that the above condition is satisfied efficiently reduce development of silver halide emulsions containing at least 50 mol% silver chloride, there being a reduction in contrast providing a linear sensitometric curve over a good latitude with negligible speed penalty.

Abstract: A silver halide color photographic material which comprises a support having provided thereon at least one silver halide photographic emulsion layer containing a dispersion of oleophilic fine particles containing at least one diffusion-resistant, oil-soluble coupler capable of coupling with an oxidation product of an aromatic primary amine developing agent to form a substantially non-diffusible dye and at least one water-immiscible coupler solvent having a melting point of up to 100°C and a boiling point of 140°C or higher, said oil-soluble coupler being represented by following general formula (Cp-I), (Cp-II) or (Cp-III) and said dispersion of the oleophilic fine particles being a dispersion prepared by emulsifying and dispersing a solution of a mixture comprising at least one said coupler, at least one coupler solvent, and at least one water-insoluble and organic solvent-soluble homo- or co-polymer comprising at least repeating units having no acid groups in the main or side chain (at least 35 mol %). This photographic material provides dye images having excellent image preservability. Symbols in the general formulae (Cp-I), (Cp-II) and (Cp-III) have the same meanings as those defined in the specification.
