PHOTOSENSITIVE BODY AND IMAGE FORMING METHOD

摘要

PURPOSE:To form the polymerized image which is excellent in contrast, lightness and saturation by laminating a photosensitive layer and a polymerizable layer, exposing the layers with light existing in a specific wavelength region and heating the layers to polymerize the regions of the polymerizable layer corresponding to the unexposed parts of the photosensitive layer. CONSTITUTION:The photosensitive layer 1 and the polymerizable layer 2 are laminated, are exposed by the light exiting in the 400 to 900nm wavelength region and are heated to 60 to 180 deg.C, by which the polymn. of the regions of the polymerizable layer 1 is utilized. The polymerized images having the good contrast are more early and stably obtd. In this way and the visible images and color images having the excellent lightness and saturation and the stability thereof with age are obtd. without being affected by the black color of the silver images.
