    摘要: The invention relates to an ultrahigh contrast photographic material comprising a support bearing a silver halide emulsion layer, containing a hydrazide nucleating agent in the emulsion layer or a hydrophilic colloid layer, characterised in that the nucleating agent of formula (I) comprises (a) two nicotinamide moieties, which may be the same or different, which are linked by a linking group, and (b) a hydrazide moiety linked to only one of the nicotinamide moieties. The nucleator of formula (I) may be in combination with a nucleator of formula (II) which comprises a dimeric molecule comprising two monomers linked by a linking group, each monomer of which (a) may be the same or different and (b) comprises a hydrazide moiety and a nicotinamide moiety. The photographic material provides unexpectedly good nucleation in the absence of, or with reduced amounts of, booster and in a developer whose pH is variable, and further with lower chemical spread and pepper fog. When the synthesis provides both a compound of formula (I) and (II), the products can be used directly without a separation step, providing a cost advantage.

    摘要: Color photographic elements, especially color photographic papers, can be more rapidly color developed (up to 25 seconds) in the presence of a color developing solution containing a selectively diffusible color development photochemical such as a development inhibitor. Despite the shortened processing time, color balance within the three color records of such elements is maintained. The selectively diffusible color development photochemical has size and structure that enables it to have sufficient solubility in the color developing composition, and to selectively diffuse into the topmost red-sensitive emulsion layers of the processed color papers only.

    摘要: The present invention provides a photographic element comprising a support bearing a light-sensitive silver halide emulsion layer in association with an image dye-forming coupler and having associated therewith a compound of general formula wherein R1 is an unsubstituted or substituted alkyl group, aryl group or 5-10 membered heterocyclic ring group containing one or more heteroatoms selected from N, O and S; each R2 is independently selected from hydrogen, halogen, and substituted or unsubstituted alkyl, aryl, alkyl- or aryl-sulfamoyl, alkyl- or aryl-sulfonamido, alkyl- or aryl-carbamoyl, alkyl- or aryl-carbonamido, alkenyloxy or 5-10 membered heterocyclic ring group containing one or more heteroatoms selected from N, O and S; each Y is independently selected from the groups consisting of —NHSO2 and —SO2NH; wherein the hydrogen therein has a pKa value of less than 9; n is an integer from 1 to 20; x is an integer from 1 to 6 and wherein the compound is ballasted. The addenda of formula (I) can significantly increase the image dye yield and improve robustness to process pH variation, without adverse effects on coupler or dye stability, dye hue and/or speed, in a simple, cost effective way.
