Problems solved by technology

[0003] However, the screen protectors currently used in the market are prone to air bubbles when pasted and are not easy to discharge, which affects the aesthetics of the product after the film is applied. Moreover, the screen protectors currently used have low light transmittance and poor scratch resistance, and the protective film is still easy to be damaged by fingers. , pendant and other scratches, thus affecting the service life of the LCD screen
[0004] In addition, because people's requirements are getting higher and higher, ordinary screen protectors on the market can no longer meet people's requirements, especially young people, who pursue fashion and diversification, have become the first choice for them and most people to buy various screen protectors. The ultimate goal, so the development of high-performance, diverse screen protectors has broad market prospects

Abstract

The invention discloses a scratch-resistant color screen protective film. The protective film mainly comprises a main film, an assembly glue layer, an assembly glue protective film, a scratch-resistant layer with colors, a protective film glue layer and a scratch-resistant layer protective film. The protective film has the following advantages: the protective film is easy to assemble; the bubbles can be rapidly and automatically eliminated; the screen surface is free of residual glue after the protective film is removed; the protective film can be repeatedly pasted and used after being removed from the screen and has the functions of resisting scratch, resisting wear and preventing fouling; and as different colors of organic dyes and other dispersing aids are added to the scratch-resistant layer, the whole protective film has the characteristics of transparent and bright colors, strong fashion sense and the like after uniform dispersion and can be widely used for protecting the screens of various liquid crystal displays. The manufacturing method of the scratch-resistant color screen protective film is simple, easy to operate and suitable for industrial production.

Description

technical field [0001] The invention relates to a protective film, in particular to a color anti-scratch screen protective film for protecting a liquid crystal screen and a manufacturing method thereof. Background technique [0002] With the vigorous development of electronic technology, electronic products such as mobile phones, MP4, MP5, cameras, digital video cameras, and notebook computers are being introduced from old to new. In order to prevent the screen surface of electronic products from being scratched or worn, which will affect the use, a screen protective film is generally attached to the screen surface of electronic products. [0003] However, the screen protectors currently used in the market are prone to bubbles when pasted and are not easy to discharge, which affects the aesthetics of the product after the film is applied. Moreover, the screen protectors currently used have low light transmittance and poor scratch resistance, and the protective film is still ...
