|Applicants:||DENKA COMPANY LIMITED
|Title:||BIAXIALLY STRETCHED SHEET AND SHAPED ARTICLE OF SAME|
Provided are: a biaxially stretched sheet which is formed from a styrene resin composition and has good transparency, strength, film forming properties and formability, while having excellent productivity, heat resistance, oil resistance, appearance and antifogging properties; and a shaped article of this biaxially stretched sheet. A biaxially stretched sheet which is formed from a styrene resin composition containing a styrene-methacrylic acid copolymer and an acrylic resin, and wherein: the mass ratio of the styrene-methacrylic acid copolymer to the acrylic resin is from 90/10 to 97/3; the styrene-methacrylic acid copolymer contains a styrene monomer unit and a methacrylic acid monomer unit at a mass ratio of from 84/16 to 94/6; the styrene-methacrylic acid copolymer has a weight average molecular weight of from 120,000 to 250,000; the acrylic resin has a weight average molecular weight of from 1,000,000 to 7,000,000; and the styrene resin composition has a Vicat softening temperature of from 106°C to 132°C. This biaxially stretched sheet has a coating layer, which contains a sucrose fatty acid ester and a water-soluble polymer, on at least one surface. A shaped article of this biaxially stretched sheet.
