PURPOSE: A composition that is obtained by adding a specific polyester plasticizer, ethylene/vinyl ester copolymer resin to a vinyl chloride resin in a specific proportion, thus being suitable for forming marking films, because the composition gives moldings with an appropriately high level of toughness. n CONSTITUTION: The objective composition is obtained by mixing (A) 100pts.wt. of vinyl chloride resin containing 0W20wt% of a copolymerizing component, with (B) 10W25pts.wt. of liquid polyester plasticizer of more than 1,500 number-average molecular weight, (C) 0W10pts.wt. of other plasticizer for vinyl chloride resin and (D) 5W20pts.wt. of ethylene/vinyl copolymer resin (substantially free from thermoplastic polyurethane resin) so that the yield stress is adjusted to 1W6kg/ mm 2 . Component B is, e.g., a polyester plasticizer from a dibasic acid of 4W15 carbon atoms such as maleic acid and a dihydric alcohol of 2W20 carbon atoms such as ethylene glycol. n EFFECT: Moldings has improved adhesion to pressure-sensitive adhesive, flexibility and printability. n COPYRIGHT: (C)1985,JPO&Japio |
