Title (EN) LIGHT DIFFUSION PLATE
(FR) PLAQUE DE DIFFUSION DE LUMIÈRE
(JA) 光拡散板
Abstract:
(EN) Disclosed is a light diffusion plate (3) which is formed from a resin composition containing 100 parts by mass of a propylene resin and 0.03-10 parts by mass of a hindered amine light stabilizer having a specific chemical structure.  The light diffusion plate (3)is used in a surface light source device (1) which comprises a light source (2) that is arranged on the back side of the light diffusion plate (3).
(FR) L'invention porte sur une plaque de diffusion de lumière (3) qui est formée à partir d'une composition de résine contenant 100 parties en masse d'une résine de propylène et 0,03-10 parties en masse d'un stabilisateur de lumière à base d'amine encombrée ayant une structure chimique spécifique. La plaque de diffusion de lumière (3) est utilisée dans un dispositif de source de lumière de surface (1) qui comprend une source de lumière (2) agencée sur le côté arrière de la plaque de diffusion de lumière (3).
(JA)  本発明に係る光拡散板3は、プロピレン樹脂100質量部、ならびに特定化学構造のヒンダードアミン系光安定剤0.03質量部~10質量部を含有する樹脂組成物からなる。この光拡散板3は、その背面側に配置された光源2を備えた面光源装置1に用いられる。
