Abstract: A coating composition for forming a light scattering layer includes a light transmitting resin containing an acrylic resin, and resin particles containing a fluororesin having a refractive index of 1.40 or less. The resin particles are contained in the amount of 100 to 400 parts by mass per 100 parts by mass of the light transmitting resin on a solids basis.

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.
Abstract translation: 涂料组合物包括含羟基的丙烯酸树脂，氟树脂和光漫射颗粒，并且含羟基的丙烯酸树脂的重均分子量在10,000至30,000的范围内，羟值在一定范围内 为14〜70，其中氟树脂与含羟基的丙烯酸树脂（氟树脂/含羟基的丙烯酸树脂）的质量比为5/95〜50/50。 涂料组合物可以提供能够均匀地漫射光的光漫射特性，同时有效地遮蔽光源图像。

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.
