ABSTRACT:
An image forming medium includes a base coated with a layer of at least three kinds of microcapsules encapsulating photocurable compositions for forming a color image thereon. The photocurable compositions contain a radical-polymerizable unsaturated compound, a photosensitizer and a photopolymerization initiator. The photosensitizer may be selected from several dyes which have sensitivity to different spectra of light.
