A coating material composition include a hydroxyl group-containing acrylic resin, a fluororesin, and light diffusive particles, and the hydroxyl group-containing acrylic resin has a weight-average molecular weight in a range of 10,000 to 30,000 and a hydroxyl value in a range of 14 to 70, wherein a mass ratio of the fluororesin to the hydroxyl group-containing acrylic resin (the fluororesin/the hydroxyl group-containing acrylic resin) is in a range of 5/95 to 50/50. The coating material composition can provide the light diffusing properties capable of uniformly diffusing light while effectively masking a light source image.

The purpose of the present invention is to provide a composite pigment which can be dispersed and made into paint in a manner that saves labor compared with conventional flat emulsion paints, and which can achieve concealing properties and low glossiness (a luster reduction effect) without separately adding a matting agent. This composite pigment contains an inorganic compound and/or an organic compound, and a fixed extender pigment.

An object is to provide a plate shaped ferrite particle for a pigment, having both of electromagnetic wave shielding ability and designability, a resin molded material containing the plate shaped ferrite particle a pigment, and an electromagnetic wave shield housing for storing an electronic circuit manufactured by using the resin molded material. To achieve the object, the plate shaped ferrite particles for a pigment having a metallic luster, a resin molded material containing the plate shaped ferrite particles for a pigment, an electromagnetic wave shield housing for storing an electronic circuit manufactured by using the resin molded material are employed.

Various coating compositions are described which provide protection for polymeric films and particularly PVC films. The coating compositions include particular resin(s) and opacifying agents. Also described are coated films utilizing the compositions and methods of forming the coated films.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles dispersed in at least a portion of a polymer matrix comprising first polymer material and a sacrificial material, the sacrificial material being removable from the polymer matrix to define a plurality of pores in the polymer matrix. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. The sacrificial material may comprise a second polymer material. The compositions may define a composite having a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. Additive manufacturing processes may comprise forming a printed part by depositing the compositions layer-by-layer and introducing porosity therein.

Disclosed herein are aqueous latex compositions comprising polysaccharide particles and a polymer dispersion or polymer emulsion. In one embodiment the polysaccharide particles comprise poly alpha-1,3-glucan. Also disclosed are an adhesive, film, coating, or binder comprising the latex composition in a dry form, as well as articles comprising the adhesive, film, coating, or binder.

The present invention relates to a curable silicone rubber composition for various types of water supply components used in contact with water. The present invention also relates to a cured product of this composition, a water resistant cured silicone rubber, and use thereof. The present invention imparts good water resistance to a silicone rubber component used in contact with water, and the present invention prevents or decreases the occurrence of whitening or similar visual appearance failures, and the occurrence of insufficient strength to withstand high temperature steam.

A decorative sheet is provided that includes a paper substrate, a printed pattern layer arranged to face a major surface of the paper substrate, and a single-layer or multilayered surface protective layer arranged to face the pattern layer, the surface protective layer comprising a coating layer as an outermost layer of the decorative sheet, the coating layer being comprised of a coating containing antiviral additive particles (e.g., antiviral agent), the antiviral additive particles comprising finely divided silver. Further, the coating layer may contain a silicone-based component or a fluorine-based component, which imparts contamination resistance to the coating layer; the amount of the antiviral additive particles in the coating layer may be 0.2 mass % or more and 12 mass % or less relative to the total solid content of the coating layer; and the thickness of the coating layer may be 3 μm or more.
