PURPOSE:To make possible to obtain the high color density of the title material, even in case of developing the material at a low temp. by incorporating a latex having a specified min. film forming temp. in a photosensitive layer contg. a diazo compd., a coupling component and a color auxiliary agent. CONSTITUTION:The photosensitive layer contg. the diazo compd., the coupling component and the auxiliary agent is mounted on a supporting body, and a latex having the min. film forming temp. of >=60 deg.C is incorporated in the protective layer. And, any one of the diazonium compd. and the coupling component is enclosed in a microcapsule composed of a polyurethane or a polyurea. The copying material obtd. by the method as mentioned above, is exposed corresponding to an original, and a light irradiates a part except the image forming part of the copying material, followed by heating and developing the whole surface of the photosensitive layer. Thus, the high color density of the copying material is obtd., even in case of developing the material at the low temp. |
