Abstract

The invention provides a method for detackifying the surface of a liquid photosensitive resin letterpress, the method comprising the steps of: (1) configuring a photocatalyst solution, wherein the solute is benzophenone and its hydrocarbon derivatives, and the solvent is alcohol, ether or chloroform, The concentration is 0.1wt%-8wt%; (2) in the coating step (1), the photocatalyst solution is placed on the surface of the letterpress, and the ultraviolet light is used to detack. Adopting the photocatalyst solution of the present invention for detackification enhances the photoreaction effect, significantly reduces the viscosity of the letterpress plate, enhances the ability to transfer PI liquid during the PI printing process, and improves the printing uniformity.

Description

technical field

[0001] The invention relates to a method for tackifying the surface of a liquid photosensitive resin relief. Background technique

[0002] At present, liquid photosensitive resin letterpress (referred to as liquid plate) is mainly used in the PI (polyimide) printing process of LCD (Liquid Crystal Display) manufacturers' medium and high-end products STN (Super Twisted Nematic) and color-STN. The main component of the liquid resin raw material used is unsaturated polybutadiene resin (Unsaturated Polybutadiene Resin). The process method is to coat the resin on a special exposure equipment, and first cure and shape it after selective exposure, and then wash the plate. , drying, light treatment, post-exposure and other processes determine the final size and performance of the product.

[0003] According to the surface characteristics of the printing material (PI liquid) and substrate (ITO glass) used in the LCD industry, the surface tension of the liquid plate us...
