Abstract

The invention discloses a positive-working thermosensitive lithography printing plate material. The material comprises a hydrophillic layer base body and a thermosensitive layer covering the hydrophillic layer base body, wherein the main component alkali-soluble resin in the thermosensitive layer is composed of an IA repetitive unit, an IB repetitive unit, an IC repetitive unit and an ID repetitive unit. The material has the advantages that the plate material subjected to exposure and liquid alkali developing has high sensitivity, high screentone quality and high pressrun.

Description

technical field [0001] The invention relates to the field of printing plate materials, in particular to a positive heat-sensitive lithographic printing plate material applied to computer-to-plate making. Background technique [0002] At the end of the 1990s, computer image processing technology was still a brand-new technology, and it was a cutting-edge technology that only a few leading companies in the world had mastered. After 2010, computer-to-plate system gradually became popular in China. The continuous research and development of plate manufacturers, the continuous improvement and breakthrough of plate coating related technology by plate manufacturers, and the rapid development of computer-to-plate plate-making plates in China. [0003] The photosensitive substance used in the positive thermal plate technology is an infrared absorbing dye that matches the emission wavelength of the infrared laser. The coating material coated on the hydrophilic plate base is made by th...
