Problems solved by technology
However, the shape of the injection molded product is generally more complicated, and the product generally has multiple surfaces, and there are some depressions or corners, which are not easy to paint or cannot be painted, that is, there are coatings in the process of coating the protective layer 23 after injection molding. The dead angle is installed, and the thickness uniformity of the protective layer 23 after painting is not easy to control, resulting in a low product yield and an increase in relative cost
In addition, after injection molding, the product is painted. In order to ensure that the product surface can be covered with a coating, a wide range of coating is required, and the utilization rate of the coating is low. Moreover, the complex shape of the product surface results in a low utilization rate of the coating, resulting in product failure. 20 cost increase

Embodiment Construction
[0015] A film for in-mold decoration and its manufacturing method will be described below with examples.
[0016] Please refer to Fig. 3, a kind of in-mold decoration film 30 that the preferred embodiment of the present invention provides, it comprises a transparent substrate 31, a pattern layer 32 and a hard film layer 33, and this transparent substrate 31 comprises two opposite surfaces 311 and 322 , the pattern layer 32 is formed on one surface 311 , and the hard coat layer 33 is formed on the other surface 312 . The film provided by the invention can be used in electronic device shells and daily necessities.
[0017] The transparent substrate 31 is a planar transparent film with a thickness between 0.127mm and 0.381mm, and its material can be polycarbonate polymer. The pattern layer 32 can be an ink layer with a predetermined pattern, and its thickness is between 0.02mm and 0.03mm. The hard coat layer 33 is made by painting and baking a transparent paint. The preferred ...

Abstract
The present invention relates to one kind of inside-mold decorating membrane and its making process and mold inside decorating process. The membrane includes one transparent substrate, one pattern layer formed on one surface of the substrate, and one hard film layer on the other surface of the substrate. The membrane is made through providing one transparent substrate, forming pattern layer on one surface of the substrate, and forming one hard film layer on the other surface of the substrate. The mold with the inside-mold decorating membrane may be used in producing product with high surface hardness and low production cost.
Description
technical field [0001] The invention relates to a film for in-mold decoration, a manufacturing method thereof, and an in-mold decoration process. Background technique [0002] In-mold decoration refers to the process of forming a decorative pattern on the surface of the product when the product is injection molded in the mold. Generally, a film with a decorative pattern is formed in advance, and then the film formed with a decorative pattern is hot-pressed. To form a predetermined shape, the film is cut and then placed in the cavity of the injection molding mold, and finally the molten material is injected into the cavity, and the film is combined with the molten material to form a product with a decorative pattern. The appearance of the product made by in-mold decoration has a stronger sense of reality than that of the product formed by painting after injection molding, and the pattern does not have any adverse phenomena such as fading or falling off. It has been widely use...
