Abstract: Disclosed are porous resin particles which contain a polymer of a monomer mixture of a mono(meth)acrylate-based monomer and a polyfunctional vinyl-based monomer. The mono(meth)acrylate-based monomer contains an ethylenic unsaturated group only in a (meth)acrylic acid residue, a hydroxyl group in an alcohol residue, and at least one of an ether group and an ester group in an alcohol residue. The polyfunctional vinyl-based monomer contains two or more ethylenic unsaturated groups. The porous resin particles have a water absorption value of from more than 400 ml to 700 ml per 100 g of the particles and an oil absorption value of from more than 400 ml to 700 ml per 100 g of the particles.

Abstract: A light diffuser and its use are provided, which not only reduces a color change in a source light when the light diffuser is disposed on an optical path of a light source, but also has a good light transmission property and a good light diffusion property. The light diffuser contains a thermoplastic resin and transparent particles added thereto. The total light transmittance of the light diffuser is 75% or more. The degree of dispersion of the light diffuser is 2° or more, the degree of dispersion being defined as a transmission angle at which a light transmittance is 50% of a rectilinear light transmittance when light is emitted to a surface of the light diffuser in a direction normal to the surface. The difference between the rectilinear light transmittance at 460 nm and the rectilinear light transmittance at 580 nm of the light diffuser is 0.96% or less.
