  • Publication number: 20220009207
    Abstract: 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.

  • Patent number: 10457025
    Abstract: The present invention provides a sheet, wherein the sheet has an excellent low-gloss feeling; even when oblique light is incident on a surface of the sheet, diffuse reflection of the light is suppressed, the surface is less likely to look white when viewed obliquely, and a design represented on the sheet can be visually recognized; and the sheet has excellent designability. In the sheet, a surface of the sheet has an arithmetic average roughness Ra (JIS B0633: 2001) of 0.7 ?m or less, and the reflectance at a detection angle equal to a regular reflection angle ±5°, measured by a variable angle photometer when the surface is irradiated with incident light at an incident angle of 75°, is 50% or less of the reflectance at the regular reflection angle.

  • Publication number: 20190184688
    Abstract: The present invention provides a low-gloss decorative sheet having an appropriately low level of wiping resistance, and thereby enables strongly adhering grime to be easily wiped off, thus being excellent in terms of easy cleanability. The present invention provides a decorative sheet comprising a base material sheet and at least a surface-protecting layer on the base material sheet, (1) the base material sheet being a thermoplastic resin sheet, (2) the surface-protecting layer having a surface free energy of 40 mJ/m2 or more, (3) an arithmetic average roughness (Ra0.08) measured on the surface side of the surface-protecting layer at a cutoff value of 0.08 mm with an evaluation length of 0.4 mm by a measurement method in accordance with JIS B0601:2001 being 0.60 ?m or less, and (4) a specular glossiness on the surface-protecting layer side of the decorative sheet at an incident angle of 60° being 23 or less.
