PROBLEM TO BE SOLVED: To obtain durability at high temperature and in high humidity and easy sliding, easy adhesion, and antistatic properties by a method in which at least on one side of a polyester resin, another polyester resin having smaller melting energy than the resin is laminated, and a water-soluble or a water- dispersing resin not containing inactive particles is laminated on the latter polyester resin. SOLUTION: At least on one side of a polyester resin A, a polyester resin B having smaller melting energy than the resin A is laminated, and a water-soluble or water-dispersing resin not containing inactive particles is laminated on the resin B. Polyethylene terephthalate is named as the resin A, and a resin which is obtained by a method in which a 100:0-60:40 mole % mixture of terephthalic acid and isophthalic acid is used as an acid component, a 100:0-60:40 mole % mixture of ethylene glycol and cyclohexane dimethanol is used as an alcohol component, and the mixtures are co-polycondensed is used as the resin B. The water-soluble or water-dispersing resin has functions including easy adhesion, antistatic, easy sliding, and mold releasing properties. |
