POSITIVE IMAGE FORMING METHOD

摘要

PURPOSE:To form a positive image free from image defect by making the shearing stress of a releasing layer and a photosensitive resin layer below a specific value by a temp. change and transferring only the image from a laminated body of a photosensitive material and a picture receiving paper to the picture receiving paper. CONSTITUTION:An image forming material is formed by successively laminating the releasing layer and the positive photosensitive resin layer in the order on a substrate. And the image forming material having >=15g/mm<2> shearing stress of the releasing layer and the photosensitive resin layer in the atmosphere of <=30 deg.C is exposed to form the image and the laminated body is formed by laminating the image forming material and the image receiving paper with heating under a pressure. Only the image is transferred on the picture releasing paper by releasing the laminated body and furthermore the releasing layer from the substrate in the atmosphere of >=60 deg.C, in which the shearing stress is made <=7g/mm<2>. The photosensitive resin layer is stuck to the releasing layer with sufficient strength at a room temp. of <=30 deg.C and high precise dot pictures are formed on the substrate provided with the releasing layer by exposing and developing.
