Abstract
An object of the present invention is to provide a methacrylic resin composition which exhibits excellent flexibility, elasticity, impact resistance, and plasticity and moldability while transparency inherent to methacrylic resins is maintained. A methacrylic resin composition to be produced is composed of 10 to 99 parts by mass of a methacrylic resin (A) containing not less than 80 mass % of a methyl methacrylate unit and 90 to 1 part by mass of a block copolymer (B) containing 10 to 60 mass % of a methyl methacrylate polymer block (b1) and 90 to 40 mass % of an acrylate polymer block (b2) and having a refractive index of 1.485 to 1.495 (the total of (A) and (B) is 100 parts by mass).
