Abstract

PURPOSE: To provide the titled sheet having high light transmittance and excellent light diffusion properties, exhibiting little changes in these characteristics by drawing, and suitable for the illumination use, by dispersing calcium carbonate having specific particle diameter.
CONSTITUTION: A sheet composed of an acrylic resin dispersed with calcium carbonate having an average particle diameter of 1W20μ in an amount of 10W20g/ m2. The acrylic resin is a polymer obtained by the polymerization of methyl methacrylate monomer, a monomer mixture composed mainly of methyl methacrylate, or their partial polymer, and having a viscosity-average polymerization degree of 2,000W20,000. The thickness of the product is arbitrary, e.g. 0.8W10mm (sheet) or 25W800μ (film).
