ABSTRACT:
A diffusion transfer color photosensitive material is disclosed, comprising a support having thereon at least light-sensitive silver halides, binders and nondiffusible dye-providing compounds capable of releasing or forming a diffusible dye, corresponding to or counter-corresponding to the progress of conversion of the siliver halide into silver through reductive reaction, which contains as a trapping agent at least one compound represented by the following formula (I) to prevent the generation and/or the transfer of dyes in the white area without causing the lowering of image density:
