PROBLEM TO BE SOLVED: To obtain a sheet having excellent rigidity (modulus of elasticity) and optical characteristics (transparency and luster) and improved molding and processing characteristics. SOLUTION: A resin composition constituting this sheet comprises four components of (A) a styrenic resin containing no rubber component, (B) a copolymer composed of 97-70 wt.% of an styrenic monomer (b-1) and 3-50 wt.% of an unsaturated carboxylic acid ester monomer (b-2), (C) a mineral oil and (D) organic or organic particles and satisfies (1) (A) the compounding ratio of the component (A) to (B) by weight of 0.75<=A/(A+B)<=0.98, (2) the amount of the component (C) added of 0.03-0.5 pt.wt. based on 100 pts.wt. of the composition (A)+(B), (3) the amount of the inorganic or organic particles (D) added of 0.0005-1.5 pts.wt. based on 100 pts.wt. of the composition (A)+(B) and (4) the component (A) containing neither (b-1) nor (b-2). |
