Abstract

PURPOSE:To obtain a printing plate esp. fit for corrugated cardboard printing by blending urethane-modified acrylate, a copolymerizable monomer and a photopolymerization initiator further blending a photopolymerization initiating assistant as required and applying ultraviolet rays with a specified intensity for a specified time to form a cured layer of a specified thickness. CONSTITUTION:Polyalkylene glycol A with a MW of 400-5,000 and aromatic oligoester B with a MW of 200-2,000 and an acid value of 20 or less are reacted in an A to B molar ratio of 0.25-4.0 and a weight ratio of 1.0 or more to form a compound having two or more groups, in the molecule, which react with isocyanate. This compound is then reacted with organic diisocyanate and an alcoholic OH group-containing acrylate compound to obtain urethane-modified acrylate. To this acrylate are added a copolymerizable monomer such as alkyl acrylate and a photopolymerization initiator such as benzoin ethyl ether or further added an initiating assistant as required. By applying ultraviolet rays under specified con- ditions such as an intensity of 2,000muw/cm<2> and a time of 60sec a 0.40-1.40mm thick high-grade printing plate free from a cupping phenomenon, etc. is obtained.
