Problems solved by technology

However, since the added anti-glare particles and the coating resin material are different substances, there is a certain difference in their refractive index, and the anti-glare particles will cause a certain degree of refraction, large-angle scattering and absorption of the transmitted light, making the cured film The light transmission performance will be affected, which directly causes poor clarity of the IMD printed pattern. Simply put, the printed pattern is not correct and opaque, such as the black background is not black, gray and black, etc.

Abstract

The invention provides a frosted hardened film for in-mold decoration, comprising a support body and a transparent hardened layer, wherein convex-concave veins are stamped on the transparent hardened layer through stamping and secondary ultraviolet curing; the thickness of the transparent hardened layer is 10-20 microns; and the transparent hardened layer comprises the following components in parts by weight: 35-50 parts of polyurethane acrylic prepolymer, 1-10 parts of grafted modified acrylic monomer, 0.5-7 parts of light initiator, 0.05-2 parts of flatting agent and 30-60 parts of solvent. According to the product provided by the invention, a frosting effect is generated, and the problems that printed patterns of the existing product do not have right colors and are not transparent are solved; and furthermore, the requirements on molding and tensile performances of the IMD (In-mold Decoration) can be met. The frosted hardened film for the in-mold decoration can be widely applied to surface decoration of the products.

Description

technical field [0001] The invention belongs to the technical field of in-mold decoration (IMD), in particular to a frosted hardened film for in-mold decoration. Background technique [0002] In-mold decoration (IMD) refers to the process of forming a decorative pattern on the surface of the product when the product is injected into the mold. Generally, a film with a decorative pattern is formed in advance, and then the film with a decorative pattern is heated. Compression molding to form a predetermined shape, the film is cut and then placed in the cavity of the injection molding mold, preferably molten material is injected into the cavity, the film combines with the molten material and forms a product with a decorative pattern. The appearance of products made by in-mold decoration has a stronger sense of reality than products that are patterned by painting after injection molding, and the pattern does not have any adverse phenomena such as fading or falling off. It is wide...
