RESIN COMPOSITION HAVING LIGHT-GUIDING ABILITY, AND LIGHT GUIDE PLATE AND SURFACE LIGHT SOURCE BODY COMPRISING SAME

摘要

The present invention provides a resin composition offering both a high level of light-guiding ability and high flowability, as well as a light guide plate and surface light source body comprising the same. The present invention is a resin composition having light-guiding ability, containing (A) a polycarbonate resin (A-component) and (B) a polycarbonate/polydiorganosiloxane copolymer resin (B-component), wherein the resin composition has a viscosity-average molecular weight in the range of 1.2×104 to 1.3×104, and the B-component is a polycarbonate/polydiorganosiloxane copolymer resin where a polydiorganosiloxane domain having a mean size of 0.5 to 40 nm is present in a matrix of polycarbonate polymer.
