Abstract: An image receiving sheet for thermal transfer recording is disclosed. The image receiving sheet comprises a lower layer and an image receiving layer on the support, and variation of position of point of a needle satisfies the following conditions when the needle having a diameter of 1 mm is touched on the image receiving sheet with a load of 10 g and the temperature is risen at a rate of 5° C. per minute; {(Position at 25° C.−Position at 30° C.)/Position at 25° C.}×100%≦5% {(Position at 25° C.−Position at 130° C.)/Position at 25° C.}×100%≧50%.

Abstract: Disclosed is provide an intermediate image receiving sheet for a laser thermal transfer recording method, which can easily transfer an image to even a rough surface paper with high quality and stable repeatability, and can use a variety of papers to produce an image proof which yields results similar to a print made in a production run.

Abstract: Disclosed is a heat sensitive planographic printing plate material comprising a support and provided thereon, a heat sensitive layer containing 10 to 98 weight % of at least one hydrophilic resin selected from the group consisting of gelatin, polyvinyl alcohol and carboxymethyl cellulose, and 2 to 50 weight % of a cross-linking agent cross-linking the hydrophilic resin.

Abstract: A light sensitive composition comprising (a) a vinyl type polymer having a unit represented by the following Formula (1) and a carboxyl group, (b) a monomer, oligomer or polymer containing at least one polymerizable double bond in its molecule, (c) a photopolymerization initiator and (d) a polymerization inhibitor capable of trapping a radical, ##STR1##
