A carbon decorative panel includes a carbon-toned irregular surface. The carbon-toned irregular surface has a plurality of unit patterns that constitute a weave of pseudo carbon fiber bundles presenting carbon fiber bundles in a pseudo manner, as the protrusions and depressions that form the carbon-toned pattern. A plurality of unit patterns each have a top portion positioned at the center in the extending direction of the pseudo carbon fiber bundle and a pair of curved portions positioned on both sides of the top portion in the extending direction and formed in a curved shape. The curvature of a pair of curved portions in the section along the extending direction of a pair of curved portions is greater on the center portion side than on the end portion side in the crossing direction that crosses the extending direction.

There is provided a keyboard instrument in which a plurality of white keys and a plurality of black keys are arranged in a widthwise direction, a total width dimension of the plurality of white keys that constitute one octave is set to 160 mm or less, and a width dimension of an upper surface of each of the black keys is set to 9 mm or more and 10.5 mm or less.

There is provided a hydraulic transfer film which consists of a laminate that has, on a water-soluble film, both an extension-inhibiting resin layer and a luster ink layer containing a luster pigment and a binder resin, wherein: the laminate has protrusions and recesses on the surface opposite to the water-soluble film; and the resin forming the extension-inhibiting resin layer contains a resin (A) having a glass transition temperature of 80 C. or higher. There is also provided a process for manufacturing the same; and a process for producing a decorated molded product, using the transfer film.

A decorative sheet includes a decorative layer. Holes arranged in a plurality of directions are provided in the decorative layer. An average of values of an array pitch of holes arranged in a first array direction, in which the array pitch has a least value among the plurality of directions, and a standard deviation thereof, and an average of values of an array pitch of holes arranged in a second array direction, in which the array pitch has a second least value among the plurality of directions, and a standard deviation thereof, meet particular conditions.

A method for producing a hydrophobic or superhydrophobic surface topography on a smooth or structured surface of a pressing tool in the form of a pressing plate, endless belt, or embossing roller for producing material plates, plastic films, separating films, PVC surfaces, and LVTs (luxury vinyl tiles), includes the following steps: preparing a surface template having a microstructure, making an impression of the surface using a resin, scanning the molded surface using a 3-D microscope, converting the digitalized data from the scanning process with depth measurement into grayscale bitmaps, using the grayscale bitmaps to control the machining process of an abrasive surface treatment or to apply a mask for chemically processing the pressing tool in order to produce the surface topography. For this purpose, either the pressing tool is partially covered with a mask and subjected to an etching operation or the determined grayscale bitmap data are used to control an abrasive machining head.
