Embodiment Construction

[0013] see figure 1 and figure 2 According to the preferred embodiment of the present invention, the casing 100 includes a decorative film 10 and a body 20 formed on the decorative film 10 by in-mold injection molding. The decoration film 10 includes a film 12 , a silicon monoxide layer 14 , a two-component polyester ink layer 16 and a protective layer 18 covering the surface of the film 12 sequentially. The film 12 is made of transparent or translucent plastic material, such as polyethylene terephthalate (polyethylene terephthalate, PET). The silicon oxide layer 14 and the two-component polyester ink layer 16 both play a decorative role, and the silicon oxide layer 14 and the two-component polyester ink layer 16 form hydrogen bonds and silicon-oxygen bonds at their interfaces. The protection layer 18 is connected to the body 20 to prevent the two-component polyester ink layer 16 from being damaged during the subsequent injection molding process.

Abstract

The invention discloses a decorative film which comprises a thin film body, a silicon oxide layer and a two-liquid type polyester ink layer. The silicon oxide layer and the two-liquid type polyester ink layer are sequentially arranged on the surface of the thin film body, and siloxane coupling agents are added into ink which forms the two-liquid type polyester ink layer. The invention further provides a shell body with the decorative film.

Description

technical field [0001] The invention relates to a decorative film and a casing using the decorative film. Background technique [0002] In-mold decoration technology has the advantages of good decorative effect and high wear resistance, and is widely used in the manufacture of mobile phone casings. In order to make the surface of the mobile phone have a special metallic luster, a film layer with a metallic luster, such as a silicon oxide layer, can be vacuum sputtered on the surface of the transparent film of the in-mold decorative film. However, the adhesion between silicon oxide and the existing two-component polyester ink decoration layer is poor, which limits the application of silicon oxide sputtering layer in the field of in-mold decoration. Contents of the invention [0003] In view of this, it is necessary to provide a decorative film that can effectively solve the above problems. [0004] In addition, it is also necessary to provide a casing to which the above-m...
