Abstract

The invention belongs to the field of screen protection films of 3C (Computer, Communication and Consumer Electronics) products and in particular relates to a blue-proof hardening film. In order to overcome the defects of complex processes, high cost or low ultraviolet absorption rate of a current blue-proof protection film. The invention provides a blue-proof hardening film. The blue-proof hardening film comprises a base film; an ultraviolet-proof coating and a blue-proof hardening coating are sequentially arranged on one side of the base film. The blue-proof hardening film is simple in structure, high in hardness, excellent in adhesive force, high in transparency, capable of effectively absorbing blue light, facilitating the protection on the eyes of users, absorbing more than 99% of ultraviolet light and facilitating deceleration of the aging of the skins of the users, and widely applicable to the field of the screen protection films of the 3C products.

Description

technical field [0001] The invention belongs to the field of screen protective films for 3C products, and in particular relates to an anti-blue light hardening film. Background technique [0002] With the increasingly powerful functions of 3C products such as mobile phones, computers, and TVs, people spend more and more time facing these products every day. They do not know that the light emitted by the screens of these products contains ultraviolet rays that can damage the skin and blue light that can damage the eyes. , Therefore, if some of the ultraviolet and blue light emitted by the screens of these products are filtered out, it will be very beneficial to the protection of the skin and eyes. [0003] At present, as everyone's awareness of anti-blue light continues to increase, anti-blue light screen protective films have also come out one after another. The base film is a protective film compounded by the action of an adhesive. Although the ultraviolet absorption rate ...
