Problems solved by technology

Due to the use of inorganic particles, the system has dispersion stability problems
In addition, the performance of the coating composition does not reflect the elastic self-healing performance and the scratch resistance of sharp objects except for the abrasion resistance of the paper tape.
Moreover, the composition contains an organic solvent, which has the disadvantages of environmental protection, production safety, complicated process and high cost.
In addition, the paint is also only suitable for ordinary occasions, and it is not mentioned that it is suitable for brightness-enhancing film paint

Abstract

The invention relates to a high refractive index self-repairing brightening coating composition. The coating composition comprises the following components and parts by weight: 15-55 parts of photocurable resin, 10-70 parts of photopolymerizable monomer, 2-4 parts of photoinitiator, 0.05-1 part of auxiliary agent; It is a sulfur-containing high refractive index difunctional acrylate unsaturated polymer with both soft and hard segment structures. The high refractive index self-healing and brightening coating composition of the present invention can be coated on the optical-grade PET plastic substrate; after ultraviolet light curing, the coating has a high refractive index, excellent elasticity, and has excellent adhesion, Wear and scratch resistance.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet curing coatings, in particular to a high refractive index self-repairing brightening coating composition. Background technique [0002] As an important accessory of the LCD display, the backlight module plays a very important role in the brightness of the LCD display. People try various ways to improve LCD display brightness from the aspect of backlight module. Adding a brightness enhancing film between the light guide plate and the lower polarizer is one of the methods [0003] The general brightening coating is made of ordinary photocurable resin combined with a large amount of high refractive index diluting photocurable monomer to achieve the purpose of increasing the refractive index. However, due to the high shrinkage rate of the monomer after photocuring, it is easy to cause the adhesion of the coating to the substrate to decrease and cause chipping. In addition, in the assembly line ...
