摘要： A multilayer silver halide color photographic element comprises a support having coated thereon a silver antihalation layer, an interlayer, at least two red-sensitive silver halide emulsion layers, at least two green-sensitive silver halide emulsion layers a yellow filter layer, and at least two blue-sensitive silver halide emulsion layers, wherein a silver halide emulsion layer or a nonsensitive layer adjacent thereto comprises a bleach accelerator releasing coupler of formulaA-(TIME).sub.n -S-X-Rwherein A represents a coupler residue releasing from (TIME).sub.n -S-X-R upon reaction with the oxidation product of a color developing agent; TIME represents a timing group releasing S-X-R with delay under developing conditions; n represents 0 or 1; X represents a divalent linking groups consisting of an alkylene group containing 1 to 8 carbon atoms; and R represents a group selected in the group consisting of a), b) and c): ##STR1## wherein R.sub.1 represents hydrogen or a monovalent chemical group, n represents 0 or 1, Z represents the atoms necessary to complete a 5- or 6-membered ring or a fused ring, and R.sub.2 and R.sub.4, equal or different, each represents hydrogen, an alkyl group, an aryl group, --SO.sub.2 R.sub.4 or --COR.sub.4, wherein R.sub.4 represents an alkyl group or an aryl group. The invention provides reduction in residual silver levels after processing, without deleteriously affecting sensitometric properties and color reproduction performance of the photographic element.

摘要： The present invention refers to a silver halide photographic element containing a support having coated thereon at least a silver halide emulsion layer spectrally sensitized with a sensitizing dye according to the formula (I): ##STR1## wherein Z represents the atoms necessary to complete a 6-membered nitrogen-containing heterocyclic nucleus; at least 2 members of R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 --but not R.sub.1 and R.sub.2 together--represent an organic group carrying a water-solubilizing group in free acid form, in salt form or in latent form, and are same or different, the members of R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 that do not represent a said organic radical carrying a water-solubilizing group represent hydrogen, an alkyl group, an alkenyl group or an aryl group; and n is 0 or 1.The silver halide photographic material has the advantage to have a broad sensitivity in the red portion of the spectrum. It can be exposed to laser beam sources in the range of 600-700 nm.
