FLEXIBLE POLYPROPYLENE-BASED RESIN COMPOSITION, FILM OR SHEET AND SURFACE PROTECTING FILM OR SHEET COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a resin composition effective in improving weather resistance of a molding product composed of a flexible polypropylene-based resin composition, especially a surface protecting film or sheet having a bonding layer, an ink layer and a substrate formed on the surface thereof and the film or sheet comprising the resin composition. SOLUTION: (1) This resin composition is obtained by compounding 100 pts.wt. of a flexible polypropylene-based resin having (a) >=150 deg.C melting peak temperature measured with a differential scanning calorimeter and (b) 200-700MPa tensile elastic modulus with 0.05-5 pts.wt. hindered amine-based light stabilizer or (2) the resin composition is prepared by compounding a benzotriazole-based ultraviolet light absorber with 100 pts.wt. of the above flexible polypropylene-based resin. (3) The film or sheet comprises the above resin composition (1) or (2).
