Title:
RESIN COMPOSITION FOR LIGHT DIFFUSION PLATE AND LIGHT DIFFUSION PLATE
Document Type and Number:
Japanese Patent JP2009126996
Kind Code:
A
Abstract:
To provide a light diffusion plate having low water-absorbing property, high hardness, and excellent heat resistance.
A resin composition for the light diffusion plate is obtained by blending 0.1-10 parts by weight of a light diffusion agent selected from partially cross-linked siloxane-based polymer particles, acrylic polymer particles and calcium carbonate with 100 parts by weight of a resin composition, obtained by blending 20-80 parts by weight of a methyl methacrylate-styrene-based copolymer and 80-20 parts by weight of a methacrylic acid-styrene-based copolymer. The light diffusion plate is obtained by molding the resin composition for the light diffusion plate into a plate-like form having a thickness of 0.5-3 mm.
