PROBLEM TO BE SOLVED: To obtain an acrylic resin material having moldability required for injection molding of a large-sized thin photoconductive plate such as a photoconductive plate for a liquid crystal display, mechanical strength, reliability and high transparency. SOLUTION: This acrylic resin for a photoconductive plate comprises 75-90 wt.% of a methyl methacrylate unit and 10-25 wt.% of an alkyl acrylate monomer unit containing a 1-8C alkyl group and has 30-70 mL/g reduced viscosity measured in chloroform at 25 deg.C, <=3.0 thermal decomposition indexαand <=10,000 particles/g of very small foreign matters having 0.5-25μsize measured by very small particle counter. |
