ABSTRACT:
A method of peel development comprising laminating an image-forming material comprising a transparent support and a photopolymerizable composition layer on the surface of a substrate on which an image is formed, imagewise exposing the image-forming material, and peeling the support from the substrate together with the unexposed areas of the photopolymerizable composition layer while leaving the exposed areas thereof on the substrate, wherein the cohesive strength of the photopolymerizable composition layer is set such that the force required to separate the unexposed areas from the exposed areas is at least 1.0 kg/mm.sup.2 and the peeling operation is performed while maintaining a peel angle (.alpha.) of the support to the substrate within the range of 0.degree.<.alpha..ltoreq.90.degree.. This method enables the formation of sharp images on the substrate while allowing for the easy separation of the unexposed areas from the exposed areas.
