Abstract:
1. A light diffusion film comprising: a light diffusion layer; and a base film obtained by molding an aromatic polycarbonate resin composition, comprising: a resin mixture; and a compatibilizer (C); wherein a content of the compatibilizer (C) is 1 to 30 parts by mass with respect to 100 parts by mass of the resin mixture, and the resin mixture comprises: 60 to 99 mass % of (A) an aromatic polycarbonate resin; and 1 to 40 mass % of (B) a styrene-resin consisting of a homopolymer or copolymer obtained by polymerizing at least one styrene monomer of formula (IV): wherein R f is an integer of 0 to 5; with the proviso that when multiple R 7 's are present, each R 7 is independent of each other; and wherein the compatibilizer comprises a block or random copolymer obtained by copolymerizing an aromatic vinyl monomer of formula (I) and an acrylate monomer of formula (II): wherein R a is an integer of 0 to 5, R R wherein R b is an integer of 0 to 5, with the proviso that, when multiple R 4 's are present, each R 4 is independent of one another wherein the light diffusion layer is directly applied to at least one surface of the base film or optionally, applied after a corona discharge or undercoating treatment of the base film.
