发明名称 Color diffusion transfer photographic material
摘要 A color photographic material for diffusion transfer which comprises a support having thereon at least one light-sensitive silver halide emulsion layer containing a combination of a reducible dye providing compound represented by the following general formula (I) and an electron donor, said reducible dye providing compound releasing a diffusing dye when reduced, wherein at least one layer of silver halide emulsion layers contains a silver halide emulsion obtained by treating a silver halide emulsion, previously chemical sensitized in the presence of a sensitizing dye, with a solid adsorbent to desorb a part or the whole of the adsorbed dye. PWR-(Time)t-Dye(I) wherein PWR represents a group which releases -(Time)t-Dye when reduced; Time represents a group which releases Dye through subsequent reactions after -(Time)t-Dye is released from PWR; t represents an integer of 0 or 1; and Dye represents a dye or a precursor thereof.
