[0127] Next, examples of the present invention will be described.
[0128] This example is an example of producing a decorative sheet and using the decorative sheet to produce a decorative molded article.
[0129] Such as Figure 1 ~ Figure 4 As shown, the decorative sheet 1 of this example forms the curved portion 19 by vacuum forming or thermocompression forming, and then, the base resin 2 is injection-molded on the back side 19 in the molding die 5, so that it is combined with the base resin 2. integrated and used.
[0130] Such as Figure 5 As shown, the decorative sheet 1 is formed by sequentially laminating the base-side adhesive layer 11, the porous decorative sheet 13, the filler layer 14, and the protective layer side from the back side 19 integrated by injection molding the base resin. The adhesive layer 15 and the transparent surface protection layer 16 are integrated. The substrate-side adhesive layer 11 is composed of a substrate-side adhesive layer 111 and a ...

Abstract
The present invention provides a decorative sheet which enables to produce a decorative molded article with excellent design property, even if the sheet is employed to a decorative molded article requiring deep drawing, and the decorative molded article using the decorative sheet. There is provided a decorative sheet used by forming a curved portion by injection-molding a base material resin to be integrated with the base material resin. The decorative sheet is formed by integrally laminating a base material-side adhesion layer, a porous decor sheet, a protective layer-side adhesive layer, and a transparent surface protective layer from the rear surface side in this order. The protective layer-side adhesive layer is formed by curing a moisture curing type of transparent polyurethane adhesive and the surface protective layer contains polymethylmethacrylate, a composite resin of polycarbonate and polybutylene terephthalate or a composite resin of polycarbonate and polyethylene terephthalate as a main component, and has a glass transition point of 90 to 130[deg.] C. There is provided a decorative molded article obtained by forming a curved portion on a decorative sheet by injection-molding a base material resin to a rear surface side of the decorative sheet in the mold.
Description
technical field [0001] The present invention relates to a decorative sheet and a decorative molded article, wherein the decorative sheet is formed with a curved portion by vacuum forming or thermocompression forming, and then the base material is injection-molded on the back side in a molding die to be integrated with the base material resin In other words, the decorative molded article is formed by integrating the decorative sheet and the base resin. Background technique [0002] In the interior parts of automobiles such as armrests, decorative molded products formed by in-molding decorative sheets are used. The decorative sheets are used as decorative elements, and solid wood veneers (porous decorative sheets) are used. . [0003] Currently, when making decorative moldings, such as Figure 12 As shown in (a), first, a solid wood veneer 92 with a thickness of approximately 200 to 500 μm is prepared as a porous decorative sheet. [0004] Then, if Figure 12 As shown in (b)...
