Abstract

The invention relates to a light-transmitting film for displaying gradient colors and a preparation method and application thereof. The light-transmitting film comprises a light-transmitting bottom color layer and a spectrum modification layer; the light-transmitting bottom color layer is provided with a color developing surface and a color matching surface opposite to the color developing surface, and the spectrum modification layer is located on the color matching surface; the spectrum modification layer comprises a spectrum modification layer main body and a plurality of spectrum absorbers, the spectrum absorbers are distributed on the color matching surface, and the spectrum modification layer main body is filled between the adjacent spectrum absorbers. When light sequentially passes through the spectrum modification layer and the light-transmitting bottom color layer, the spectrum absorbers can absorb part of spectrum, and the spectrum which is not absorbed matches the bottom color displayed by the light-transmitting bottom color layer, so that the color developing surface of the light-transmitting bottom color layer shows a color different from the bottom color, and the gradient color effect of the color developing surface is achieved. The surface of the light-transmitting film does not need to be subjected to color modification, the problems of color fading, color changing and the like are not prone to occurring in the using process, and therefore the stability of the gradient color changing effect can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of optical functional films, in particular to a light-transmitting film for displaying gradient colors and a preparation method and application thereof. Background technique [0002] With the advancement of production technology, the colors of products are becoming more and more diverse. Among the diverse colors, gradient color, as a special apparent color, has received more and more attention. Compared with a single color, the gradient color is displayed in multiple colors; compared with the color matching, the color transition of the gradient color is softer. In the traditional method of realizing gradient color, it is often based on the color modification of the surface, the stability of the gradient color obtained in this way is poor, and problems such as fading and discoloration are prone to occur during use. Contents of the invention [0003] Based on this, it is necessary to provide a light-transm...
