Color photographic element providing improved dye stability |
摘要 |
A silver halide color photographic reflection print element comprises a paper support impregnated or coated with a substance that lowers its oxygen transmission rate and its oxygen leak rate, at least one polyolefin-containing layer containing a total of at least 70 g/m2 or a polyolefin coated on the paper support, and at least one color-forming silver halide emulsion layer, said emulsion layer or layers overlying a polyolefin-containing layer. In one embodiment, the paper support is impregnated with a substance that lowers its oxygen gas transmission rate to less than 1 cc/m2/day and its oxygen leak rate to less than a 25 cc/m2/day. The support has low permeability to oxygen and to water vapor. The silver halide color photographic element produces a dye image with improved resistance to fading by light, particularly under conditions of prolonged exposure to low-intensity light.
