<p>PURPOSE:To obtain the titled composition which causes neither blocking nor changing of a printed matter with time, has excellent thermal transfer characteristics at low temperatures, and serves to an improvement in working environment, labor saving, etc., by mixing a specified ultraviolet-curing resin with a copolyester soluble in said resin. CONSTITUTION:An ultraviolet-curing resin (A) is obtained by mixing 10-70wt% (based on resin components) homopolymer and/or copolymer of a compound of the formula (wherein R1 is H or CH3; R2 is a C1-20 alkyl, a cycloalkyl, an aralkyl or an aryl) (a), a photopolymerizable (meth)acrylate (b) having 1-3 photopolymerizable double bonds in a molecule, and 0.05-20wt%, based on the total of components (a), (b), and B mentioned below, photo-initiator (c) (e.g., propiophenone). Then, 95-60pts.wt. component A is mixed with 5-40pts. wt. copolyester (B) which is soluble in component A and is prepared by synthesis from one or more saturated polybasic carboxylic acids (derivatives) and one or more polyhydric alcohols.</p> |
