Description of the invention: • Technical field to which the invention pertains The invention belongs to the technical field of In-m〇ld decoration (IMD), in particular to an in-mold decorative injection molding (IMD). The cured film and the method for producing the same, the cured film of the present invention can avoid the cracking phenomenon of the cured film surface during the in-mold decorative injection molding (IMD) process deep molding, and the in-mold decorative injection molding method can be widely applied. Decorative layers for various products. [Prior Art] φ 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. The advantages of In-mold decoration (IMD) are suitable for plastic products of 3C, home appliances, LOGO nameplates and automotive parts, especially the popular mobile phone peripherals and various instrument panels. In-mold decorative injection molding (imd) can replace many traditional processes, such as thermal transfer, spray coating, printing, electroplating and other decorative methods. In particular, you need a variety of color images, backlights, and related products. In-mold decorative injection molding (I rib) • It is a relatively new automated production process. Compared with other processes, in-mold decorative injection molding can reduce the production steps and reduce the components of the parts, so it can save production quickly. Time and cost, while also improving the quality, increasing the complexity of the image and improving the durability of the product, applied to the appearance of the product, in-mold decorative injection molding (ι rib), is the most efficient method, it It is applied on the surface of the film by printing, hot pressing, punching, and finally combined with plastic to eliminate the secondary operation procedure and man-hours, especially in the case of backlighting, multi-surface, rib interference, etc. When the process cannot be processed, it is also using the in-mold decoration injection molding (the timing of the process.) The patent has been obtained 5 (5 1298043 Patent Publication No. 00462914 "In-mold film decorative injection molding method for galvanic electromagnetic interference" For example [Refer to the patent publication data of November 2001], the invention comprises the following steps: Step 1: Decorative film: in a transparent film-like film One side printing required pattern; Step 2: coating the shielding layer: further coating a metal shielding layer capable of shielding electromagnetic interference on the finished film; Step 3 · Film preforming · film to be coated with the shielding layer Insert the mold, according to the design of the fitting to thermoform the desired appearance; Step 4: Cut, trim and position in the injection molding mold: trim the pre-formed film cutter to the size of the injection cavity, and then place it into the mold And fixed in the injection molding cavity; Step 5: Injection molding: the hot melt resin is sprayed on the side of the formed/special film P by the injection molding machine, so that the hot melt is solidified and integrated with the film, and finally the finished product is self-assembled. The invention is completed by taking out the injection molding cavity, and completing the steps of the present invention. Announcement No. 9 "The method for manufacturing the outer casing of the leg covering and the surface decoration" patent [refer to the information of the announcement on May 11, 2, 3] The EMI shielding layer can be formed into a plastic film mainly through a step of forming a plastic film step, a B. molding EMI shielding layer step, a c coating step layer step, and a D. molding outer layer step. Between the layer and the inner layer of the na, according to this, a finished product with better brain shielding, no EMI shielding layer, no wear and tear, and a beautiful appearance can be formed; further, the valve film It can be directly molded with a predetermined decorative surface, and the leg covering layer is attached to the decorative surface of the plastic film (on the plastic fine _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In order to meet the actual needs of production and transfer. For example, the in-mold decorative injection molding process film can replace the traditional 6 1298043 film printing, hot pressing material, lyophilized decoration. This process uses the inner and outer layers of the product to protect or resist Scratch or color beautification, use = car parts, equipment appearance, mobile phone, notebook computer....... The same IMD in-mold decoration injection molding process can process plastic film with printing, coating or pigmenting The function is to achieve the decorative effect, and the surface of the film for the decorative molding process can have a three-dimensional color, a metal appearance or a pattern or a pattern. However, often in portable electronic products, the outer surface material needs a harder function to resist scratching. The traditional process can provide the surface of the hardened layer after the object is formed, but this is an environmentally friendly A process that is polluting and expensive. Another convenient choice is to apply a single-mask surface-hardening coating to a film having a molding function. However, in the high-temperature and high-pressure molding stage, the cured film should have a function that the surface hardened layer can not be broken. The maximum hardness of the film is limited by the draw ratio (maximum draw ratio is about 1.2), and there is no hardened film supply with good function on the market. For use in larger draw ratios (deep molding), Aut〇type > International offers a method of hardening the surface layer after UV film formation, but this process requires a special and troublesome process. The process can be completed without economic benefits. The above is the biggest missing of the current technology, which is a difficult problem to be overcome in the industry. SUMMARY OF THE INVENTION In view of the lack of conventional technology, the researcher of the present invention has accumulated many years of experience in the design and manufacture of adhesive film products. After continuous research and improvement, the invention has been successfully developed and published in the world.

The art method forms a hardened layer having different thick rider patterns. In the large stretched Beer area, the continuous change in the thickness of the hardened layer can be reduced by 15% to 95%, and preferably from 2% to 6%. Another main object of the present invention is to provide a "hardened film structure for the decorative injection molding" which is mainly provided with a thickness, a hardness and a predetermined geometry at a predetermined position of the embossable plastic film which is formed by the decorative decoration. The hardened layer of the hardened layer, which is thinner than the predetermined area, and has a thickness reduction, reduction/turtle 4 generation and continuous maintenance of the coating, while maintaining a good appearance, which can be reduced by 1 Brother and the coating thickness of the coating, the cured film of the invention is in the in-mold decorative injection molding (the deep cracking phenomenon can be avoided when the process is deep-formed, and the in-mold decorative injection molding process can be widely applied to various products. [Embodiment] In order to achieve the above-mentioned technical means of the present invention, an embodiment will be exemplified, and the method, structure and effect achieved by the present reviewer can be better illustrated by the following description. Under the known feasible process, if the thickness of the hardened film layer is reduced, the hardness will decrease while the 'crack resistance capacity will increase. The method of this (4) is as follows: Inventive Hardening Lin (2) is a thermoformable plastic film attached to an in-mold decoration and fired into a coffee. (1) Two [Please refer to H. This is a thermoformable film that can be thinner than the outer casing of the product or the inner 1279043 spacer. 】, and has a predetermined geometric shape, especially formed on the plane of the relatively flat plastic film (1). The present invention is firstly applied to the predetermined position of the thermoformable plastic film (1) for in-mold decorative injection molding. Forming a layer of hardened film (2) of appropriate thickness, hardness and predetermined pattern, next to the area of large stretch area (10) [such as in the concave and edge regions of the plastic film], forming a section with a decreasing thickness Hardening Lin (10)), the continuous change of the thickness of the hardening (10)) can be reduced by 15 to 95%, and preferably 20 to 60%, to reduce cracking and maintain the coating even while maintaining a good appearance, which can Reducing the sharp and discontinuous coating thickness, although the large stretch area area (1 〇) will be thinner, these are often not important areas and require less scratch resistance. Finally, it is cured by curing (such as heat hardening or ultraviolet irradiation to form a suitable hardness), and the thus formed heat-pressable plastic film containing the cured film layer can be used for in-mold decorative injection molding. Further, one or more alignment marks may be previously set at predetermined positions of the thermoformable plastic film (1) so that the cured film layer (2) is formed at a correct predetermined position. In addition, the thickness appearance and correct pattern of the cured film layer (2) are of course dependent on the rheological and thermoforming conditions of the plastic film itself in the plastic film (1), but in most cases, the requirements of the compounding conditions are not so important. The invention can form a predetermined pattern on the hot pressable plastic film (1). The formation of the hardened 'hardened film layer (2) can be formed by printing (for example, screen printing, gravure printing, letterpress printing, lithography). Appropriate graphics and thickness, or cover uncoated areas, many regular geometries 'like rectangles can use a variety of block coating methods (eg 1290443 USP5360629, USP6139637), which can be used on sheet or roll materials 'Other methods such as changing the size of the screen for printing, or changing the gap between the coating heads when applying the mold can be carried out on the thickness of the hard coating process. The aforementioned alignment mark can be the same step or different steps of the lion, and after formation, such as printing or other alignment device, the hard layer can be cured by various methods including thermal hardening or ultraviolet irradiation to form an appropriate hardness. Further, the manufacturing method of the present invention for changing the thickness in the large stretch ratio area (10) of the plastic film is as follows: 1. In the block coating method, the change is made in the large stretch ratio area (10). The spacing (slQt gap), the coating head spacing ((10) Youqing) and the control method in the UlL are made into a flattened geometric rectangular rectangular hardened film layer (20) [see the second figure]. 2. In the large stretch ratio area (10) in a point-like manner, such as lithography or letterpress or lithography, etc., by changing the size of the print, so that the large stretch ratio in the _ domain or recess or work area The area (10) constitutes a different hardened film (2 〇) thickness [see the third figure]. 3. Using the masking method, using spray, overspray, that is, the thickness of the center is thick and thin, in the area of large stretch ratio area (1〇), to achieve control thickness increase and decrease [please refer to Four pictures]. 4. The thickness reduction of the area of the large stretch ratio area is changed by using the thickness reduction of the edge portion of the transfer printing plate. 1298043 5·For complex geometry, the same pattern process or different pattern process can be used to form a large stretch ratio area (10) for different hardened film layers (20). See the fifth picture]. For example, on a 100//m polycarbonate film, a ίο# m acryl-based hardener is applied in a relatively flat area, in a large stretch ratio area (a radius of about 3 to 5 legs after forming) Only 3//m acrylic hardener is applied, and the flat area after UV curing is more than the standard 1H hardness, and the hardness in the large stretch area is 1H or less. After hot plastic forming, the polycarbonate The film (ie, the thermoformed plastic film) has a smooth surface and has no visible cracking defects. Referring to the first view of the first embodiment of the present invention, a top view and a cross-sectional view of the present invention are mainly provided for the appropriate thickness, hardness and predetermined position of the hot pressable plastic film for in-mold decorative injection molding. a hardened layer (2) of a geometrical shape having a descending thickness (20) in a predetermined large stretch ratio area (1) of the plastic film (1), the thickness of the cured film layer (20) The continuous change can be reduced by 15 to 95%, and preferably 20 to 60%, to reduce the occurrence of cracks and to maintain a complete coating while maintaining a good appearance, which can reduce the sharp and discontinuous coating thickness. When the cured film of the present invention is formed in the in-mold decorative injection molding (IMD) process, the cracking phenomenon of the cured film surface can be avoided, and the in-mold decorative injection molding process can be widely applied to the decorative layers of various products. If it is a formable plastic film with a hardened film coating, it does not need to be hardened after molding, and it does not cause visible crack lines in the large stretched area. 11 1298043 The advantages of the present invention are as follows: . In the 比较 (U), which is relatively flat (ie, the position of the predetermined hardened film layer), a higher hardness can be obtained, and the measurement range of the hardness of the pen is in the middle of the yeah and the maximum is available. Resistance to performance. 2. Unobservable shortcomings such as cracks or defects in the edge zone of the face forming. 3. Elasticity in selecting the material of the cured film layer. The above-mentioned "Ben (4)" is a kind of "hardening film that should be shot and molded". It has never been seen in the publications of _ outside, and it has been novel and special. It is clear that the company’s technology has been lost, and it has reached the tenth purpose. It has also been filled with the requirements of the invention patents, and the application has been filed according to law. I would like to ask your review committee to give a review and give the patent in this case. The above-mentioned ones are only for the purpose of the present invention, and are not intended to be used for the purpose of arresting, and are not limited to the details of the changes in the scope of the invention. It is intended to be included in the scope of the patent of the present invention.
