ABSTRACT:
An image recording material formed with a support, a photosensitive composition layer formed on the support, and a mono-particle layer of solid particles of different optical transmittances formed on the photosensitive composition layer. When the recording material is exposed to light, the firmness with which the photosensitive composition holds the solid particles varies locally from point to point in accordance with the exposure energies of light passed through the solid particles. Thus by causing the dissolving force of the solvent or other physical forces to act on the photosensitive composition, the particles held weakly are selectively removed from the recording material, whereby an image is formed by the particles left on the recording material. The recording material on which the image has been formed can be used as a printing form as it is or by being subjected to simple after-treatment.
