さみ実用的でない。[Industrial Field of Application] The present invention relates to improvement of a decorative sheet for molding, and painting using the same also includes a method for manufacturing molded products. [Prior Art] It is common practice to apply a decorative sheet to the surface of a molded product to create a beautiful design. Recently, it has become possible to create deep and beautiful designs by forming fine irregularities on the surface of decorative sheets to change the degree of gloss. This is called an ``embossed pattern.'' Taking advantage of the phenomenon that generally a glossy surface appears raised and a non-glossy surface appears sunken, the embossed pattern is created by combining prints with different levels of gloss. can be given. This effect can be further enhanced by combining the sizes of the printing inks, for example by using silk screen printing to raise the glossy areas to add actual irregularities. However, even if decorative sheets for molding are painted at the same time as injection molding or applied to molded products by vacuum forming, the irregularities on the mold surface will be removed when the sheet is pasted onto the molded product. The residual stress in the unevenness forming area is released by heat, and the unevenness is lost. For example, in the case of injection molding painting, if the surface of the injection mold is rough, the decorative sheet portion of the molded product will also be rough, and if it is mirror-finished, the molded product will also be mirror-finished. If the mirror surface or fine irregularities that are to be formed on the surface of the molded product are prepared in advance on the mold surface, the desired gloss can be imparted and a product with the desired embossed feel can be obtained. must be manufactured, which is expensive and impractical.

The purpose of painting using is to provide a method for manufacturing molded products. [Means for Solving the Problems] The decorative sheet for molding of the present invention has a basic structure as shown in FIG.
An embossed pattern is printed on the ink using a curable resin and cured by an appropriate means to form a cured printed layer (3),
This is laminated with an opaque plastic base film (1). "Embossed pattern" is a pattern that has an appearance similar to embossing by forming a pattern using ink with different degrees of gloss as described above. For example, the conduit part of a wood grain pattern is Ink υ was printed, and other parts were printed with gloss ink, making the conduit part appear to be sunken. The embossed pattern may be formed by printing two or more curable inks of different gloss on the surface film, but in some cases some of the inks may not be curable. Such cases include, for example, gloss ink used when injection molding is performed using mirror-finished molds. Alternatively, as shown in Figure 2, a hardened printing layer (3) is provided on the surface film (2) using curable ink, and a pattern printing layer (4) is formed on the surface film (2) and the base film using ordinary ink. An embossed pattern may be formed between the pattern printing layer (4) and the cured printing layer (3). The ink forming the cured printing layer may be ionizing radiation-curable, thermosetting, or acid-curing, and is, for example, an ink using epoxy resin, acrylic resin, urethane resin, polyester, or urea-melamine resin. The base film and surface film are made of polyvinyl chloride,
Polystyrene, polyphenylene, nylon or ABS
Use a thermoplastic resin film such as resin. The thickness thereof is preferably selected from a range of 50 to 500 μm, taking into consideration strength when used as a decorative sheet and ease of printing. In order to make parts other than the cured printing layer matte, a matte material such as silica or calcium carbonate may be kneaded into the base film. If this method is adopted, the degree of gloss in parts other than the cured printed layer will be less likely to change due to heat and pressure during molding, and a decorative sheet can be obtained that is less likely to become glossy during molding. The amount of the matting material to be blended may be selected depending on the desired degree of matting, and is usually in the range of 10 to 100 parts by weight per 100 parts by weight of the base film material. It is preferable that the decorative sheet for molding has a thickness of about 200 to 500 μm so that it will not tear when it is attached to a molded product. On the other hand, thick sheets are not easy to print. Therefore, as shown in FIG. 2, printing of the cured printing layer (3) and the pattern printing layer (4) is performed on a thin film, that is, the base film (1) and the surface film (2).
It is recommended to then line it with a sheet (5) of plastic with good moldability. Examples of plastics with good moldability include polyvinyl chloride, polystyrene, polypropylene, nylon, and ABS resin, with ABS resin being particularly suitable. The first method of manufacturing a molded article with a painting according to the present invention is to place the above-mentioned decorative sheet for molding in an injection mold, inject mold the synthetic resin, and integrate the decorative sheet for molding with the molded product. Consists of things. Depending on the shape of the molded product, it is preferable to pre-form the decorative sheet for molding. The second method of producing a molded article with a painting according to the present invention is to apply an adhesive to the back side of the decorative sheet for molding described above, perform vacuum forming using the molded article as a mold, and then create a decorative sheet for molding. It consists of deforming it into the same shape as the molded product and adhering it to the molded product. A typical technique is called "rOVL molding", in which the interior of a box with a molded product placed inside is divided into upper and lower halves using a decorative molding sheet, and the sheet is heated while the upper and lower compartments are evacuated. The method is to soften it, then put the royal chamber in a vacuum state and the upper chamber in a pressurized state. A simple method can be to cover a molded product placed on a table with a decorative sheet for molding, heat the sheet to soften it, and then evacuate the space surrounded by the table and the sheet.

面に与えることができるのである。In the decorative sheet for molding of the present invention, at least a portion of the embossed pattern is formed using curable ink, thereby successfully eliminating the influence of the surface condition of the mold and processing conditions. In other words, even when a pattern is formed using a cured resin, even when it is applied to a mold, the unevenness of the mold surface no longer appears on it, and even when heated, the surface does not change and retains its original fine unevenness. is maintained. In this way, the embossed pattern provided on the decorative sheet can be directly applied to the surface of the molded product.

沢度が８の浮造調の木目模様をもつものであった。[Example 1] A colored transparent film (manufactured by Riken Vinyl Industries) of polyvinyl chloride (hereinafter referred to as rPVcJ) (plasticizer-containing FF1101) hr) with a thickness of 0.2 m was used as the surface film, and a matting material was added to the isocyanate-curing type. The conduit portion of the wood grain pattern was gravure printed using urethane liquid ink, and then the ink was cured. A colored film (same as above) made of PVC (same as above) with a thickness of 0.1 rMl was used as a base film, and the portions other than the wood grain conduits were gravure printed using printing ink "Case XJ" (manufactured by Showa Ink Industries). The above two types of films were bonded under heat and pressure to form a decorative sheet for molding of 1 q. The surface gloss of this sheet was 15 in the conduit pattern part and 70 in other parts. The decorative sheet and the plastic film were layered, and molded using a vacuum forming method using a mold with a surface gloss of 100 or higher under conditions of 150'C x 10 seconds, and heated to form a laminate molded product. The glossiness of the surface of the molded product was 16 for the conduit pattern portion and 70 or more for the other portions. The glossiness was measured according to the comparison glossiness measurement method of JIS-28741.
