HEAT-SENSITIVE COMPOSITION FOR IMAGE FORMING ON A PRO-ENVIRONNMENT THERMAL CTP PLATE

摘要

PURPOSE: An environment-friendly heat-sensitive composition is provided to enable the manufacture of a high quality printing plate by a small amount of laser beam irradiation. CONSTITUTION: A heat-sensitive composition for forming an image on an environment-friendly thermal CTP plate comprises infrared absorption dye and resin, and further metal particles. The metal particles are at least one selected from the group consisting of copper(Cu), zinc(Al), tin(Sn), magnesium(Mg), manganese(Mn), chrome(Cr), iron(Fe), titanium(Ti), nickel(Ni), aluminum(Al), gold(Au) and silver(Ag).
