<P>PROBLEM TO BE SOLVED: To provide an acrylic fine particle which can be suitably used as a diffusing agent for diffusion film due to excellent dispersibility of a film such as a diffusion film. <P>SOLUTION: The acrylic fine particle is formed by polymerizing a monomer including (meth)acrylate and a crosslinking agent. The crosslinking agent includes a first crosslinking agent including at least three or more (meth)acrylic groups, and one functional group selected from the group consisting of -OH and -COOH. The coefficient of variation (C. V) of volume average particle size of the acrylic fine particle is 20-60%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
