Abstract

The invention discloses a processless thermal sensitive plate used for direct printing on a printer. The processless thermal sensitive plate comprises a support body, a thermal sensitive layer and a protective layer, wherein the thermal sensitive layer mainly comprises 30-70% of water soluble thermo-crosslinking polymer, 1-15% of cross-linking agent, 10-30% of polyfunctional group monomer, 1-20% of thermal sensitive initator and 1-20% of infrared light radiation absorbing dye according to percentage by weight based on the composition solid total weight. The shortcomings of low plate developing capacity and bad printing durability in the existing processless thermal sensitive CTP (computer to plate) technology are solved.

Description

technical field [0001] The invention belongs to the technical field of lithographic printing, and relates to a heat-sensitive plate that can be directly printed on a machine without processing. Background technique [0002] Lithographic printing technology has moved from traditional laser phototypesetting film copying PS plate technology to computer-to-plate technology (CTP technology for short), and CTP plate materials are gradually becoming popular. There are many types of CTP plates, and the more popular ones include silver salt diffusion CTP plates, UV-CTP plates, purple laser polymerization CTP plates, thermal CTP plates, etc. The most widely used one is thermal CTP plate. [0003] CTP plate making technology requires a development process with a developer containing a variety of toxic organic substances or strong alkalis, and there are environmental problems caused by the treatment of toxic and harmful waste liquids. At present, the development of a new generation of...
