The present invention provides a decorative board capable of exhibiting excellent weather resistance even in a depression of a pattern of protrusions and depressions even in a case where the pattern of protrusions and depressions is formed on the outermost surface of a transparent resin film, a transparent resin film, and a method for producing a decorative board. Provided is a decorative board including: a substrate; a picture layer; and a transparent resin film, in a stated order in a thickness direction, the transparent resin film comprising at least a thermoplastic resin layer and having a pattern of protrusions and depressions on a side opposite to a picture layer side, the decorative board further comprising at least one layer containing an ultraviolet absorber between the picture layer and the thermoplastic resin layer.

Decorative board, transparent resin film, and decorative board production method

The present invention provides a decorative sheet with excellent flame retardance and high sharpness such that patterns are clearly visible and discoloration is suppressed. The present invention provides a decorative sheet characterized by comprising one or more thermoplastic resin layers selected from the group consisting of a transparent resin layer, a base material sheet, and a synthetic-resin backer layer, wherein (1) at least one of the thermoplastic resin layers contains a metal phosphinate-based flame retardant; and (2) the transparent resin layer and the base material sheet contain at least one resin selected from the group consisting of polyolefin-based resins and polyester-based resins.

Decorative sheet and decorative plate

The present invention provides a transparent resin film excellent in weather resistance even in a case where a pattern of protrusions and depressions is formed on the surface for the purpose of imparting excellent design properties, a decorative board including the transparent resin film, and a method for producing the decorative board. Provided is a transparent resin film for protecting a picture layer on one side of a substrate, including at least: a surface protective layer; and a transparent resin layer, laminated on each other, the transparent resin film having a pattern of protrusions and depressions on a surface protective layer side, the transparent resin film having a thickness at a depression of the pattern of protrusions and depressions of 100 μm or larger, the transparent resin film containing an ultraviolet absorber.

Transparent resin film, decorative board, and method for producing decorative board

The invention provides a transparent resin film that has a smooth surface on a side to be laminated on a substrate to prevent entering of air bubbles when bonded to a substrate and has a pattern of protrusions and depressions on a side opposite to the side to be laminated on a substrate to provide high design quality, a method for producing the transparent resin film, and a decorative material. The invention relates to a transparent resin film to be laminated on a substrate including a picture layer, the transparent resin film having a pattern of protrusions and depressions with a maximum height Rz of 20 μm or higher and 200 μm or lower on a side opposite to a side to be laminated on the substrate, the transparent resin film having a maximum height Rz of 20 μm or lower on the side to be laminated on the substrate.

Transparent resin film, transparent resin film production method, and decorative material

Provided is a method for producing a decorative material, including: a preparation step of preparing sheet printed matters each including a substrate and a picture layer on one surface of the substrate and a roll of a transparent resin film having a first surface and a second surface opposing to each other, the first surface having a pattern of protrusions and depressions, the second surface having a pattern of protrusions and depressions that is shallower than the pattern of protrusions and depressions on the first surface; an application step of winding off the transparent resin film from the roll of a transparent resin film and applying an adhesive to the second surface of the transparent resin film; and a bonding step of bonding the second surface of the transparent resin film and the picture layer of each of the sheet printed matters with the adhesive.

Method for producing decorative material

The present invention provides a transparent resin film that is capable of imparting excellent design properties to a decorative board and is excellent in adhesion to a picture layer, a decorative board including the transparent resin film, and a method for producing the decorative board. Provided is a transparent resin film for protecting a picture layer provided on one side of a substrate, the transparent resin film having a pattern of protrusions and depressions on a picture layer side, the pattern of protrusions and depressions having a maximum height roughness Rz defined in JIS B 0601 (2001) within a range of 15 &#x3bc;m or larger and 70 &#x3bc;m or smaller.

A printed woodgrain pattern and a lustrous solid printed layer are formed by printing on the back surface of a transparent thermoplastic resin film to obtain a printed film. The printed film and a colored thermoplastic resin film are superposed, the printed film and the colored thermoplastic resin film are laminated to obtain a laminated structure and, at the same time, the laminated structure is embossed from the side of the colored thermoplastic resin film by a doubling embossing method with an embossing die provided with an embossing pattern of ridges and furrows to obtain a decorative sheet. In the decorative sheet, a second and a third embossed pattern each having a cross section having a smooth outline expressed by a periodic function or a pseudoperiodic function are formed in the interfaces between the colored thermoplastic resin film and the lustrous printed layer and between the lustrous printed layer and the transparent thermoplastic resin film, respectively.
