More Information
Summary:A photographic element comprising a support bearing one or more silver halide emulsions at least one of which comprises at least 50% silver chloride in association with one or more image dye-forming couplers and one or more DI(A)R couplers of formulae I or II:wherein:TIME is a timing group andR1, R2, Z, n, and j are as defined in the specification,wherein the DI(A)R coupler(s) in association with an emulsion comprising at least 50% silver chloride comprise at least about 25% to about 90% of the total amount of coupler in association with that emulsion and the total amount of coupler is the sum of the number of moles of image coupler(s) and the number of moles of the DI(A)R couplers in association with that emulsion.
