Color diffusion transfer element with spacer layer containing pigment and scavenger for oxidized developing agent |
摘要 |
A photographic element for a diffusion transfer process is described, comprising at least one support having thereon (1) a layer containing a dye-providing compound capable of releasing or forming a diffusible dye or a precursor thereof as a result of development, (2) a silver halide photographic emulsion layer which is in a complementary color relationship with the dye-providing compound, and (3) a substantially non-sensitive spacing layer between the layers (1) and (2) containing a solid pigment, a hydrophilic colloid, and a nondiffusible compound capable of undergoing a redox reaction with the oxidation product of a silver halide developing agent under an alkaline condition.
