The solid content contains a resin component (A) and a filler (B). The resin component (A) includes at least one of a fluorine-containing copolymer (a1) or a silicon-containing copolymer (a2). The fluorine-containing copolymer (a1) includes a fluorine-containing segment and an acrylic segment containing no fluorine or silicon. The silicon-containing copolymer (a2) includes a silicon-containing segment and an acrylic segment containing no fluorine or silicon. The filler (B) has a mean particle size falling within a range from 10 nm to 200 nm.

Antifouling coating composition, optical member, and light fixture

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.

Coating material composition, and light-diffusing member manufactured using said coating material composition

A light diffuser includes: a thermoplastic resin base which has a thermal expansion coefficient of at least 4&#xd7;10/K and at most 8&#xd7;10/K; and a light diffusion layer which is disposed on a surface of the thermoplastic resin base and includes an acrylic resin film and an acrylic resin particle, the acrylic resin film including one or more acrylic resins having a glass transition temperature of at least 30&#xb0; C. and at most 50&#xb0; C., the acrylic resin particle being included in the acrylic resin film and having an average particle size of at least 1 &#x3bc;m and at most 15 &#x3bc;m.
