Document Type and Number:
WIPO Patent Application WO/2016/186121
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a resin composition exhibiting excellent transparency and heat resistance, and which has no externally visible defects when injection molded. This resin composition contains: a styrene resin (A) comprising a copolymer including an unsaturated dicarboxylic acid anhydride monomer unit; and a transparent resin (B) other than the styrene resin (A). When measured according to ASTM D1003 at a thickness of 2mm, the resin composition has a total luminous transmittance of at least 88% and a haze value of at most 0.3%. The styrene resin (A) is preferably a copolymer comprising 45-90 mass% of a styrene monomer unit, and 10-55 mass% of an unsaturated dicarboxylic acid anhydride monomer unit, a (meth)acrylic acid monomer unit, a (meth)acrylic acid ester monomer unit, etc. The transparent resin (B) is preferably at least one selected from a methacrylic resin, a methyl methacrylate-styrene copolymer, and a styrene-acrylonitrile copolymer.
