发明名称 LOW-BIREFRINGENCE RESIN COMPOSITION
摘要 PROBLEM TO BE SOLVED: To provide a resin composition formable of a thick film, having excellent shock resistance, and exhibiting low birefringence even when being molded into a plate shape with a thickness of 2 mm by using an injection molding machine or a sheet molding machine. SOLUTION: The resin composition comprises the following components as essential components: a thermoplastic resin (A) which contains a (meth)acrylate (a1) as an essential constitutional monomer; an aromatic ring-containing polyester resin (B); and a synthetic rubber (C). In the resin composition, an absolute value of a photoelastic coefficient is 7.0×10<SP>-12</SP>Pa<SP>-1</SP>. COPYRIGHT: (C)2011,JPO&INPIT
