PURPOSE:To obtain the titled drawn sheet having excellent transparency, uniform applicability of silicone oil, peelability of the sheet and releasability of stacked articles, by biaxially drawing a resin composition composed of a styrene resin having decreased rubber concentration and synthetic silicon dioxide. CONSTITUTION:The objective drawn sheet having improved applicability of a silicone oil by the minute irregularity formed on the surface of a styrene resin sheet and avoiding the defective appearance and rupture of the sheet is produced by biaxially drawing a resin composition composed of (A) a transparent styrene resin containing 0.01-0.05wt% styrene-grafted diene rubber (in terms of rubber concentration) having an average particle diameter of 1-5mum and (B) 30-300ppm of synthetic silicon dioxide having an average particle diameter of 1-5mum. |
