Abstract

A method for manufacturing a cosmetic sheet is provided that has a texture closer to the real thing and expresses good color close to the real thing, and also has excellent weather resistance for post-processing such as V-groove bending processing. To this end, a pattern layer (5) having a pattern, a transparent thermoplastic resin layer (6) containing a nano-sized nucleating agent, and a surface protection layer (7) are laminated in this order on one side of a colored thermoplastic resin layer (2), and a pattern layer (8a) is formed by using a colorless or light-colored ink and a material that has light absorption properties for light of a predetermined wavelength more than the colored thermoplastic resin layer (2), and then a pattern portion (3) for expressing a gloss matte, which is a light-absorbing area, is arranged to be synchronized with the pattern on the other side of the colored thermoplastic resin layer. After that, an irradiating light is irradiated such that the power of the light of a predetermined wavelength is stronger than the power of the light of another wavelength, and then, an embossing plate for forming an embossing shape is pressed onto the surface protection layer (7) to form an embossing portion (7a).

Method for manufacturing a cosmetic sheet, cosmetic sheet, cosmetic component, and ink for forming a pattern portion for producing a gloss matte finish. The present disclosure relates to a method for manufacturing a cosmetic sheet, a cosmetic sheet, a cosmetic member, and an ink for forming a pattern portion for expressing a gloss matte finish, and in particular to a method for manufacturing a cosmetic sheet, a cosmetic sheet, and a cosmetic member. Decorative sheets have been developed and evolved as the housing construction industry has developed. Originally, materials suited to local characteristics, such as wood and stone, were used in housing; however, with the development of the housing industry and the progress of industrialization, a transition from natural materials to artificial materials has taken place. Furthermore, in recent years, concerns that the extensive use of high-quality wood and stone could lead to deforestation and environmental problems have also been a factor in expanding the demand for decorative sheets. For example, decorative members in which decorative sheets are bonded to wood substrates such as plywood, MDF (medium-density fiberboard), and particle board, as well as resin substrates, inorganic non-combustible substrates, and metal substrates, are widely used (see, for example, Patent Document 1). In addition, the design of cosmetic sheets often imitates surfaces such as wood or stone.
