Abstract

The invention relates to the technical field of a hardening film, in particular to high-hardness and anti-dazzle hardening layer coating liquid and a hardening film. In order to solve the problems that the existing hardening film cannot realize high hardness or anti-dazzle performance at the same time, the invention provides the high-hardness and anti-dazzle hardening layer coating liquid and thehardening film. The hardening layer coating liquid contains 40 to 80 percent of acrylic ester prepolymers, 10 to 30 percent of acrylic ester monomers, 7 to 30 percent of silicon dioxide, 2 to 6 percent of photoinitiators and 0.1 to 0.5 percent of auxiliary agents in percentage by weight. The hardening layer coating liquid provided by the invention forms a hardening layer after the curing; high hardness and anti-dazzle performance are realized. The hardening film provided by the invention has high hardness and anti-dazzle protection effects.

Description

technical field [0001] The invention relates to the technical field of hardened film, in particular to a high-hardness, anti-glare hardened layer coating liquid and a hardened film. Background technique [0002] Among the many properties of LCD optical protective film, anti-glare function has become one of the most important requirements. "Glare" is the impact on vision due to the improper distribution of brightness or contrast in the field of view. The light reflected by the surrounding light source on the screen surface has a certain impact on the brightness and contrast of the image, which is called "glare" phenomenon . In particular, low-brightness displays such as LCDs are more difficult to recognize when operating under high-brightness light. Watching such screens for a long time is very harmful to the naked eye. The methods for realizing the anti-glare function of the screen include: (1) mechanically grinding the surface of the film or selectively corroding it with ...
