Description

Gradually-changed texture film

Technical Field

The utility model belongs to the technical field of a cell-phone or dull and stereotyped protection film technique and specifically relates to a protection film for electronic equipment specifically is a gradual change texture membrane that can improve color saturation.

Background

Along with the development of electronic products, the appearance is more and more light and thin, the surface treatment of the electronic products is more and more fine, in order to not scratch the surface of the mobile phone, a layer of protective film is often pasted on the surface of the electronic products, the existing protective film is generally divided into a toughened film, a frosted film, a colorful film and the like, the colorful film is generally printed by gradient ink, and the gradient effect cannot be achieved on the formed products due to the fact that the brightness of the ink is insufficient in the printing process and the color saturation of the set effect cannot be achieved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a gradual change texture membrane.

In order to achieve the above object, the utility model provides a following technical scheme:

the gradual change texture film is provided with a light-transmitting substrate, a green film is arranged on the upper surface of the light-transmitting substrate, a gradual change texture layer is arranged on the upper portion of the green film, a light plate transfer printing layer is arranged on the upper portion of the gradual change texture layer, an OCA (optically clear adhesive) layer is arranged below the light-transmitting substrate, a release film is arranged below the OCA layer, and the gradual change texture layer is composed of a plurality of gradual change texture curves which are parallel along the same direction.

Furthermore, the gradient texture layer is composed of a plurality of parallel gradient texture curves with the depth to the light and the line width distance of 0.25-0.5 mu m in sequence according to the same direction and the same color.

Furthermore, the gradient texture layer is formed by sequentially forming a plurality of parallel gradient texture curves with the depth of the curve from the deep to the light and the line width distance of 0.25 to 0.5 mu m in a plurality of colors according to the same direction.

Further, the light-transmitting substrate is a PET plate.

The utility model discloses put the good gradual change texture membrane of rendition in the worn-out fur mould, transfer glue on dripping, then put the product on it, the roller bearing pressure is passed, and the UV lamp shines the solidification, tears the glue layer of bottom, and only one deck gradual change printing ink and the not enough product of luminance just become penetrating originally this moment, and the saturation improves.
