PURPOSE: To obtain a sharp copy image by a simple process, and to form a plurality of transferred copies through repetition of transfer, by providing on a support a light and heat sensitive layer containing a heat-volatile or heat- sublimable dye, a photocurable photosensitive resin, and a photosensitizer, when needed.

CONSTITUTION: A light and heat sensitive layer containing a heat-volatile or heat-sublimable dye, a photocurable resin, such as cinnamic acid derivative or polyvinyl-p-azidobenzoate, and a photosensitizer, such as picramide, when needed, is formed on a support, such as paper or plastic film. An original drawing is overlaid on this layer, exposedto light, and then, this layer and a transfer paper for which plain paper is usable are superposed and passed between heating rollers to give a copy image. A plurality of sharp copies can be obtained by exchanging a transfer paper after one time exposure.
