PURPOSE:To manufacture an easy adhesion high strength polyester film & generating no transfer or detachment of a film in a manufacturing process, excellent in antistatic properties and having excellent adhesion to various coating materials, for example, magnetic paint. CONSTITUTION:An aq. coating soln. based on aq. polyurethane with Vicat hardness of 3X10<-4>-60X10<-4>g.f/mum at 120 deg.C is applied to at least the single surface of a longitudinally stretched polyester film and the coated film is dried to be laterally stretched. This film is further re-stretched longitudinally and, if desired, laterally to be thermally fixed. |
