Description of the Invention: [Technical Field of the Invention] The present invention belongs to the technical field of In-mold decoration (IMD), and particularly relates to an outer layer of in-mold decorative injection molding (rib rib) A method for producing a cured film having a hardened layer on the surface, and the cured film of the present invention can avoid the phenomenon of cracking of the turtle when the surface of the cured film is stretched during the in-mold decorative injection molding (IMD) process to promote the in-mold decoration injection molding ( The IMD process can be used extensively by the industry to achieve improved yield, efficiency, colorization and environmental pollution reduction. [Prior Art] According to the traditional plastic processing technology, it has gradually failed to meet the requirements of light, thin and short consumer electronic products of modern products, and is environmentally conscious. Due to the advantages of In-m〇ld decoration (IMD), it is suitable for 3C, 豕, LOGO nameplate and plastic parts of automotive parts, especially the popular mobile phone. In-mold decorative injection molding (_ can replace many T-transfer processes, such as thermal transfer, spraying, printing, electroplating, etc. In particular, it requires a variety of color images, backlights, related products.

The decorative surface, and the EMI shielding layer is combined with the decorative surface of the plastic film 1268834 (forming a predetermined pattern or color on the plastic film), thereby effectively reducing the cost and improving the manufacturing efficiency to meet the actual industrial reality. demand. As described above, 'on the portable f-type electronic product', the outermost layer of the surface must have a hardened layer to prevent surface scratching and damage the appearance or value of the product. Traditionally, there is a way to finish the shape of the object. The hardened layer is coated by a spraying method, but this method is cumbersome in process, low in yield, and causes solvent air pollution, which is an environmentally polluting and expensive process. In the right decorative injection molding (IMD) process, the use of thermoplastic film will replace traditional die-painting, hot stamping and electric mining. This process is widely used today, including > and inside and outside parts and portable electronics. Products such as mobile phones, computers, game consoles, etc. In-mold decorative injection molding (IMD) process heating plastic fine-grain printing, coating, dyeing, etc. to achieve the effect of decorative aesthetics and colorization, and then through the mold cutting, hot pressing, trimming, placement of the mold cavity Medium injection molding, the bottom layer is a compatible plastic substrate, and the inner surface of the thermoplastic film can be processed into various patterns such as color, metal surface, wood grain, etc., because the pattern color material is placed on the inner layer of the heat moldable, Has the effect of not being destroyed. Another more advantageous method is to use a thermoplastic film, first coating a hardened layer on the outer surface of the film, and the hardened layer must be cracked during hot press forming without stretching, but The maximum hardness of the hardened layer produced by the method will be closed by impurities (such as U or 1.3 times), and there is currently no hardened film supply with good function in the market. Aut〇type Internati_ offers a wide range of stretch ratios (deep-forming), which is based on coating and thermal drying.
