PROBLEM TO BE SOLVED: To provide a propylene polymer laminated sheet excellent in all of impact resistance, transparency and rigidity. SOLUTION: A surface layer and a back layer are formed from a propylene polymer compsn. prepared by compounding 2-60 pts.wt. of an ethylene/α-olefin random copolymer with a density of 0.850-0.925 g/cm3, an MFR of 0.5-30 g/10 min, a Q-value of 21.4-3.5 and an ethylene content of 99-50 wt.% with 100 pts.wt. of a propylene polymer based on an MFR of 0.5-50 g/10 min, and an intermediate layer is formed from a propylene polymer compsn. prepared by compounding 2-100 pts.wt. of an ethylene/α-olefin random copolymer with a density of 0.850-0.925 g/cm3, an MFR of 0.5-30 g/10 min, a Q-value of 1.4-3.5 and an ethylene content of 99-50 wt.% based on 100 pts.wt of a propylene/ethylene block copolymer with an MFR of 0.1-30 g/10 min and an ethylene content of 1-30 wt.% to obtain a propylene polymer laminated sheet. |
