Abstract

The invention discloses a colorful film and a preparation method thereof. The preparation method of the colorful film of the present invention includes the following steps: 1) Coating the coating composition on the substrate using the fluid shear induction force generated by the coating method to form a microstructure in which nanospheres are periodically arranged, and drying Finally, the nanospheres are regularly and periodically arranged on the surface of the substrate to form a nanosphere coating surface; 2) UV-curing the substrate containing the nanosphere coating surface obtained in step 1) to obtain the colorful film. The preparation method of the invention has a simple preparation process, and the produced film has a colorful effect, excellent mechanical properties and outstanding adhesion.

Description

technical field [0001] The invention relates to the technical field of colorful films, in particular to a colorful film and a preparation method thereof. Background technique [0002] Colorful film, also known as colorful film, iridescent film, etc., refers to the film that shows different colors as the viewing angle changes with the naked eye. Tracing back its development history, it has gone through different stages. The earliest realization of this principle is to use the light interference phenomenon produced by stacking multi-layer structures with different refractive indices. The gradual change of color can be seen under naked eye observation. At the same time, with the change of angle, It can also produce different bright color change effects. A typical representative is 3M's multi-layer co-extrusion technology, that is, through multi-layer co-extrusion of multi-layer structures with different refractive indices or even hundreds of layers of film, this technology has...
