PURPOSE:To obtain a polymer image with a smaller quantity of light for exposure and to obtain a polymer image with a small quantity of light for exposure even by a dry process by using a silver halide emulsion as a photosentive substance to sensitize a polymn. reaction. CONSTITUTION:When a photosensitive material is imagewise exposed, a latent image 4 is formed on silver halide in the exposed part. A silver image and a photopolymerizable sensitizing dye image 5 are formed in the exposed part by the following uniform heating, and a polymer image 6 is formed by the excitation of the sensitizing dye with light by the following uniform exposure. The polymer image 6 can be developed by a known method. When the image 6 is converted into a dye image by a monomer-dye bleaching method, a heat sensitive material 7 havig a heat sensitive layer 8 contg. a heat sensitive substance on the support 9 is brought into contact with the photosensitive material having the polymer and residuel monomer images. They are uniformly heated to diffused and transfer the residual monomer in the imagewise unexposed region to the part 10 of the layer 8. The heat sensitive substance bleaches the dye having developed color by heating, and bleaching is not carried out in the polymer image part (imagewise exposed region), so a heat sensitive dye image 11 is formed in the imagewise exposed region. |
