    摘要: A photographic light-sensitive element is described comprising a support having provided thereon at least one of a light-sensitive silver halide emulsion layer and an image-receiving layer, in which a layer comprising a light-reflective organic polymer is provided between the support and the light-sensitive silver halide layer or the image-receiving layer. The light-reflective organic polymer layer serves as a stripping layer without retarding image-formation.
