Abstract
Provided is a light diffusing resin composition, which, when molded into a large-plane light diffusing plate, is free of yellowing due to thermal deterioration, and can exhibit good light diffusing property, and a light diffusing plate using the resin composition. The light diffusing resin composition includes 100 parts by mass of a polycarbonate resin containing a polycarbonate copolymer (A) having repeating structural units represented by formulae (I) and (II) and 0.01 to 10 parts by mass of a light diffusing agent (B).
Claims18
A light diffusing resin composition, comprising:
- a polycarbonate composition comprising an aromatic polycarbonate resin and a polycarbonate copolymer (A) having repeating structural units represented by the following formulae (I) and (II):
- wherein the repeating structural units represented by the formula (I) and the repeating structural units represented by the formula (II) are present in a formula (I):formula (II) molar ratio of 8:92 to 12:88;
- and
- a light diffusing agent (B), the light diffusing agent (B) being present in an amount of 0.01 to 10 parts by mass relative to 100 parts by mass of the polycarbonate resin composition,
- wherein said polycarbonate composition comprises said polycarbonate copolymer (A) and said aromatic polycarbonate resin in a polycarbonate copolymer (A):aromatic polycarbonate resin mass ratio of 100:0 to 30:70.
