一、前言光敏树脂是近几年来迅速发展起来的一类高分子材料,已经在印刷及其他方面得到实际应用。用光敏树脂制作印刷版,是印刷工业的一项重大技术革新。目前世界各国应用的感光树脂印刷版,以其化学成份来看,有以醇溶性聚酰胺为主体的西德Nyloprint,美国的Tilon,日本的Toplon,我国的尼龙版;有以聚乙烯醇衍生物为主体的日本NAPP版;有以不饱和聚氨酯为主体的日本KPM2000和美国的Letterfelex;有以不饱和聚酯为主体的日本APR,和我国的感光(液体)树酯。
First, the foreword Photosensitive resin is a rapid development in recent years, a class of polymer materials, printing and other aspects have been the practical application. The production of printing plates with photosensitive resins is a major technological innovation in the printing industry. Currently used in all countries in the world of photosensitive resin printing plate, with its chemical composition point of view, with alcohol-soluble polyamide West Germany Nyloprint, the United States Tilon, Japan’s Toplon, China’s nylon version; with polyvinyl alcohol derivatives As the main body of the Japanese NAPP version; Japan has a unsaturated polyurethane KPM2000 and the United States Letterfelex; Japan has an unsaturated polyester APR, and our photosensitive (liquid) resin.
