Abstract: PURPOSE:To obtain a method for forming a sharp colored image having good contrast by using a photosensitive material for diffusion transfer having the layer constitution consisting of a photosensitive material for panchromatic diffusion transfer and back printing specification and using a silver complex salt diffusion method, etching bleach method and coloring method. CONSTITUTION:The photosensitive material for panchromatic diffusion transfer is exposed from the surface side having a silver halide emulsion layer and is superposed on an image receiving material. Both materials are passed through a processing soln. for diffusion transfer and are stripped; thereafter the direct positive type photosensitive material for diffusion transfer is used with the image receiving material on which the transferred image is formed as an original. After said phtoosensitive material is exposed from the surface side having no silver halide emulsion layer, the material is superposed on the image receiving material and is passed through the processing soln. for diffusion transfer, then the materials are stripped. The two processes, i.e.,, the process consisting in processing the image receiving material on which the transferred image is formed with an etching bleach liquid and removing the silver image and the process consisting in using a dye liquid, dyeing the image with the dye and obtaining the dye image are than executed. The binder of the silver halide emulsion layer is 0.3-5 by the weight of the silver halide in terms of silver nitrate and the coating rate of the silver halide is usually in a 0.5- about 5g/m<2> range. The sharp colored image having the excellent contrast is thus obtd.
