ABSTRACT:
A recording material comprising a support, a layer of a light-sensitive composition on the support, and a transparent film on the layer of the light-sensitive composition wherein the light-sensitive composition comprises (a) a monomer containing at least two addition polymerizable unsaturated bonds and having a boiling point of at least 100.degree. C, (b) polyvinyl butyral, and (c) a photopolymerization initiator represented by the formula: ##STR1## wherein R.sub.1 is an alkyl group which may be substituted or a vinyl-methyl group, R.sub.2 is an alkyl group, aryl group, or thienyl group, and Z is a group of non-metallic atoms required for forming a heterocyclic ring.
After the recording material is imagewise exposed to light, the transparent film is peeled off while heating at about 70.degree. to 150.degree. C, whereby a positive or negative image is formed on each of the support and transparent film.
