Embodiment Construction

[0047] see figure 1 , figure 1 A schematic cross-sectional view of a film 1 according to a specific embodiment of the present invention is shown. The film 1 includes a carrier film 12 , a structural layer 14 , a hardening layer 16 , a release layer 18 , an adhesive layer 20 , a decoration layer 22 and an antistatic layer 24 . The carrier film 12 is used to carry the multi-layer structure, and its material can be selected from polyester (Polyester, PET), polycarbonate (Polycarbonate, PC), cast polypropylene (Casted Polypropylene, CPP) or other materials that can be used to make a multi-layer structure. The thickness of the material of the structural-functional film may be between 25 microns and 200 microns, and a preferred thickness may be about 20 microns; however, the present invention is not limited thereto.

[0048] The structural layer 14 is formed on the carrier film 12 and has a first pattern. The material of the structural layer 14 mainly includes a resin 142 and a pl...

Abstract

The invention provides a thin film, a shell with a decorative pattern and a method for manufacturing the same. The thin film comprises a carrier film, a structural layer and a hardening layer formed on the carrier film as well as a release layer and an adhesion layer formed between the hardening layer and the carrier film. The structural layer is provided with a first pattern; the hardening layer comprises a recessed part and forms a second pattern identical to the first pattern. The method for manufacturing the thin film comprises the following steps of: firstly, preparing the carrier film, then sequentially forming the structural layer on the carrier film, forming the release layer on the structural layer, forming the hardening layer on the release layer and finally forming the adhesion layer on the hardening layer. The method for manufacturing the shell comprises the following steps of: attaching the thin film on a main body by the adhesion layer and peeling the carrier film, the structural layer and the release layer to obtain the shell with the decorative pattern. The hardening layer of the thin film has the protective action and a three-dimensional structure to present the stereoscopic vision.

Description

technical field [0001] The present invention relates to a film, a casing with a decorative pattern, a method for manufacturing the film and a method for manufacturing the casing, and in particular to a film with a three-dimensional pattern, a casing with a decorative pattern, a method for manufacturing the film and Manufacturing method of the shell. Background technique [0002] In-Mold Decoration (IMD) has become one of the main surface decoration technologies in recent years. It is mainly used in surface decoration and functional panels of home appliances, such as mobile phone window lenses and casings, washing machine control panels, and refrigerator control panels. , air conditioner control panel, automobile instrument panel, rice cooker control panel and other appearance parts such as panels and signs in various fields. In-mold decoration is a kind of transfer printing technology, which roughly includes flat film in-mold decoration (In-Mold Label, IML), three-dimension...
