Zusammenfassung:	PURPOSE:To provide the subject compsn. excellent in transparency, tear resistance, and weatherability and suitable for a film or sheet, etc., and to provide a film or sheet made from the compsn. CONSTITUTION:This resin compsn. contains 100 pts.wt. styrene resin, 5-80 pts.wt. hydrogenated block copolymer comprising a polymer block (A) consisting mainly of styrenic monomer units and a polymer block (B) consisting mainly of hydrogenated conjugated diene units in a wt. ratio of polymer block A to polymer block B of (10:90) to (50:50), and at least either 1-60 pts.wt. hydrogenated block copolymer comprising a polymer block (C) consisting mainly of styrenic monomer units and a polymer block (D) consisting mainly of hydrogenated conjugated diene units in a wt. ratio of polymer block C to polymer block D of (50:50) to (90:10) or 1-60 pts.wt. graft copolymer obtd. by grafting a vinyl monomer onto an olefinic resin.
