摘要:
A silver halide light sensitive photographic element is disclosed comprising a support bearing at least one yellow image forming hydrophilic colloid layer comprising yellow image dye forming couplers, at least one hydrophilic colloid layer immediately adjacent to the yellow image forming layer, and at least one adjacent cyan or magenta image forming hydrophilic colloid layer comprising cyan or magenta image dye forming couplers; wherein the yellow image forming layer is substantially free of high boiling permanent solvent, any immediately adjacent hydrophilic colloid layers and the adjacent image forming layer are substantially free of high boiling permanent solvents having a logP value of less than about 5.5, and the adjacent image forming layer contains a high boiling permanent solvent having a logP value of at least about 5.5. The photographic elements exhibit good yellow image dye light stability, which is not degraded by the presence of relatively high logP value solvents in immediately adjacent hydrophilic colloid layers and other adjacent imaging layers.
