PURPOSE:To permit the stable stripping between a release layer and adhesive layer fairly after lapse of standard stripping time by using paper made mixedly with PE as a mask material. CONSTITUTION:An image receiving sheet 7 is constituted of a base 70 made of baryta paper and an image receiving layer 71 coated thereon. A mask 8 is constituted of a mask material 80 and a weak sealing layer 81 having weak adhesive strength. The material 80 is heat-sealed to the sheet 7 via the layer 81. The layer 81 is constituted of the release layer 82 and the adhesive layer 83. The adhesive strength between the layer 82 and the layer 83 is made weakest in order to initiate the peeling from between said layers in the stage of stripping the mask 8 and the sheet 7. A rail 10 is joined securely by heat-sealing onto the material 80. The paper made mixedly with PE to have the excellent resistance to penetration of the processing liquid is used for the material 80 to prevent the penetration of the developing soln. into the weak sealing layer 81. |
