PURPOSE:To obtain a laminated film having satisfactory antistatic and adhesive properties by preparing a laminated polyester film having a specific coating layer obtd. by the coating and stretching method. CONSTITUTION:The title film comprises a laminated polyester film having a coating layer which is obtd. by the coating and stretching method and contains a polymer (A) having ionized nitrogen atoms in the main chain and a binder polymer (B). An example of the polymer (A) is an ionene polymer, a typical one being shown by the formula. The polymer (B) is an org. polymer which can be provide an aq. nonionic, cationic, or amphoteric soln. or dispersion, examples being a polyvinyl alcohol as a synthetic water-sol. polymer and starch as a natural water-sol. polymer. |
