PROBLEM TO BE SOLVED: To provide a biaxially stretched sheet which is excellent in all of oil resistance, color tone, appearance (for instance, appearance during molding and coating appearance), and antifogging properties in good balance.SOLUTION: A biaxially stretched sheet has a biaxially stretched resin layer formed by biaxially stretching a resin composition containing a copolymer which contains acrylonitrile and styrene as monomer units and has a mass ratio between the acrylonitrile and the styrene of 16/84 to 32/68; and a coating layer which covers at least one surface of the biaxially stretched resin layer, contains (A) sucrose fatty acid ester and (B) polyvinyl alcohol having a saponification degree of 85-95 mol% and a polymerization degree of 300-2,000, and has a mass ratio between (A) the sucrose fatty acid ester and (B) the polyvinyl alcohol of 80/20 to 50/50.SELECTED DRAWING: None |
