摘要:
An optical microstructure film includes a base and multiple microstructure units. The base has at least a surface. The microstructure units are disposed in an array manner on the surface of the base. Each microstructure unit is formed to be a polygonal cone having the bottom face is attached to the surface of the base. The concave region is a surface part of a pseudo-spherical structure having a lower point on the microstructure unit. The distance from the lower point to the bottom face is defined as a second height, the sum of a radius of the spherical structure and the second height is defined as a first height, and the ratio of the second height to the first height is ranged from 0.1 to 0.8.
摘要:
A method for applying a plasticity plastic film to an in-mold decoration, including the steps of: (a) providing a substrate defining a top surface and a bottom surface, printing layer and a plastic material; wherein the plasticity plastic film comprises a photo-curing multiple functional group oligomer, a thermohardening resin and a cross-linking agent, and the photo-curing multiple functional group oligomer is cross-linked with the thermohardening resin through the cross-linking agent; (b) forming the plasticity plastic film on the top surface of the substrate; (c) hardening the plasticity plastic film; (d) solidifying the plasticity plastic film to form a plasticity resin layer; (e) covering the bottom surface of the substrate with the printing layer; (f) simultaneously pressing the plasticity resin layer and the substrate to form a predetermined shape; and then (g) forming the plastic material on a bottom surface of the printing layer.
