[0002] With the popularity of intelligent equipment, as a kind of privacy protection tool, anti-peeping film has been widely used in mobile phones, tablets and laptops and other equipment. The main function of anti-peeping film is to limit the viewing angle of the screen through special optical technology, so as to prevent others from peeping the screen content.

[0003] The color layer in the anti-peeping film not only improves the visual effect of the film and reduces reflection, but also optimizes the display effect. To some extent, the color layer also helps to enhance the function of the anti-peeping layer, so that the screen content is clear and visible when viewed normally, but becomes blurred or indistinguishable when viewed from the side. The quality of the color layer directly affects the aesthetics, service life and anti-peeping effect of the anti-peeping film, so it is very important to maintain the stability of the color.

[0004] However, in the existing anti-peeping film technology, the color of the color layer remains for a short time, especially during cutting and molding, the color layer of the anti-peeping film often appears discoloration or color change, affecting the appearance and quality of the film.
