摘要： The invention provides photographic paper having increased image stability. The invention is generally accomplished by forming a paper sheet, drying said paper in a first stage to below about 10 percent water, then applying a polyvinyl alcohol solution to both sides of said paper sheet, drying said paper in a second stage to below about 5 percent water, and then applying further polyvinyl alcohol solution to said paper and drying in a third stage. The paper then may be coated to form a silver halide photosensitive color paper. The paper contains between about 4 and about 6 weight percent of polyvinyl alcohol that is concentrated near the surface of said paper. Further, the paper has a oxygen leak rate of less than about 25 cc/m.sup.2 /day and an oxygen GTR rate of less than about 1 cc/m.sup.2 /day.

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/m.sup.2 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/m.sup.2 /day and its oxygen leak rate to less than a 25 cc/m.sup.2 /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.
