Problems solved by technology

[0003] The above-mentioned plate-making process requires a film with patterns or characters. The film is easily affected by external conditions such as processing, dust, and humidity, causing disadvantages and affecting the restoration of text and patterns on the flexographic plate. At the same time, the film is attached to the flexographic plate to prevent sticking. During layer plate making, it is easy to bond the film and cause plate making defects such as light refraction and scattering, resulting in a reduction in the quality of pattern or text restoration

Abstract

Provided are a washed flexible resin plate capable of achieving laser direct imaging and a preparation method thereof. A photosensitive elastic member of the washed flexible resin plate capable of achieving laser direct imaging is composed of thermoplastic elastic member (A), polybutadiene with end achieving carboxylation (B), polybutadiene with end achieving carboxylation (C), a copolymer (D) of styrene with a side chain containing carbamic acid esterification hydrophilic poly ethoxy-acrylonitrile-poly ethoxy methyl acryloyl oxygen ethyl isocyanate, polymerizable vinyl monomers and a compound of the polymerizable vinyl monomers (E), infrared laser dye (F) and initiating system (G) composed of radical initiators and cation initiators. The system can prepare the environment-friendly washed flexible resin plate which is capable of achieving laser direct imaging and being washed by water and high in sensitivity.

Description

technical field [0001] The invention belongs to the technical field of flexible photosensitive resin plates, in particular to a water-washable flexible resin plate for direct laser imaging. Background technique [0002] At present, flexographic printing is widely used in the printing of cartons, flexible packaging, labels and other easily deformed or soft substrates. Usually, a film with a pattern or text is placed on an unexposed flexographic plate containing photoelastomer, exposed to ultraviolet light, and the transparent part of the film passes through ultraviolet light, and the initiator in the photoelastomer decomposes into free radicals, which can initiate crosslinking. Curing by monomer reaction. The area that does not pass through the ultraviolet rays cannot undergo cross-linking reaction, and the difference in solubility in the developer is used to develop a relief image containing text patterns. The plate material after development is dried, debonded, and post-e...
