PURPOSE:To form a transferred image of a high density without decreasing sensitivity and development speed by allowing a photopolymerization initiator to exist on the outside of microcapsules contg. a polymerizable compd. CONSTITUTION:Silver halide, reducing agent and the polymerizable compd. are incorporated into a photosensitive layer on a base and the polymerizable compd. is housed into the microcapsule (A). The photopolymerization initiator consisting of arom. ketone, etc., exists on the outside of the capsules A in this photosensitive layer. This initiator is preferably in the state of the microcapsules (B) separate from the capsules A and the particle size of the capsules B is preferably 0.05-50mum. The content of the initiator in the capsules B is preferably 0.5-50wt.% of the polymerizable compd. contained in the photosensitive layer. The silver halide, reducing agent and color forming material are preferably incorporated as well into the capsules A. |
