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)...
