| titleOfInvention | Silver halide light-sensitive element |
| abstract | Silver halide light sensitive photographic elements comprising a support bearing on one side thereof at least one blue-sensitive silver halide emulsion yellow-image forming layer, at least one red-sensitive silver halide emulsion cyan-image forming layer, at least one green-sensitive silver halide emulsion magenta-image forming layer, and an antihalation layer comprising a cyan filter dye coated between the support and the red-sensitive layer, wherein the green-sensitive layer comprises a four equivalent magenta image forming coupler and the cyan filter dye is of the formula (I): <IMAGE> (I) where L1, L2, L3, L4 and L5 are methine groups; R1, R2, R3 and R4 are independently H or alkyl or aryl groups; and M+ is H or a counter ion; wherein at least one of R1, R2, R3 and R4 comprises an aryl group substituted with a substituent having a pi value of less than -0.10, where pi represents the group substituent component of the hydrophobicity parameter logP. In a preferred embodiment of the invention, R3 and R4 are each H, and R1 and R2 are each phenyl groups substituted with one or more substituents, where the sum of the pi values for the substituents on each of the R1 and R2 phenyl groups is less than -0.10 at pH above 8. Photographic elements in accordance with the invention exhibit reduced dye stain after photographic processing, resulting in lower red minimum densities. Such elements also exhibit higher maximum densities, upper scale contrasts, and relative speeds compared to prior art materials. Elements in accordance with preferred embodiments of the invention exhibit improved safelight performance. |
