Abstract
The present invention discloses a decorative film comprising a colored polymer film layer and a micro/nano-structure layer on a surface of the colored polymer film layer, wherein the micro/nano-structure layer comprises a plurality of colored polymer micro/nano-structures. Due to the colored polymer film layer and the plurality of colored polymer micro/nano-structures, a color with an optical effect can be displayed, the color modulation is reduced and the process is simplified.
Claims5
A decorative film, comprising:
- a colored polymer film layer;
- and a micro/nano-structure layer disposed on one surface of the colored polymer film layer, wherein the micro/nano-structure layer comprises a plurality of colored polymer micro/nano-structures wherein the plurality of colored polymer micro/nano-structures are a plurality of convex and/or concave structures, wherein the colored polymer micro/nano-structure is a microlens, a cylindrical lens, a Fresnel lens, a CD pattern, a moth-eye structure, or a brushed pattern, wherein the colored polymer micro/nano-structure is formed from a colored polymer selected from a colored UV adhesive and a colored OCA adhesive, wherein a substrate layer is provided on another surface of the colored polymer film layer opposite to the micro/nano-structure layer, and wherein a reflective layer is provided between the substrate layer and the colored polymer film layer.
