    • 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.
    • 卤化银彩色照相反射印刷元件包括浸渍或涂覆有降低其氧气透过率和氧气泄漏速率的物质的纸张载体,至少含有至少70g / m 2的含聚烯烃的层或聚烯烃 涂覆在纸载体上,以及至少一个成色卤化银乳剂层,所述乳剂层或层叠在含聚烯烃的层上。 在一个实施方案中,纸张载体用将其氧气透过率降至小于1cc / m 2 /天并将其氧气泄漏速率降至小于25cc / m 2 /天的物质浸渍。 该载体对氧气和水蒸汽的渗透性低。 卤化银彩色照相材料产生的染料影像具有改善的抗光衰性,特别是在长时间暴露于低强度光的条件下。
