Abstract: 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.

Abstract: 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.
