Keita Toyota has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
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.
