Title:
LAMINATED FILM
Document Type and Number:
Japanese Patent JP3183084
Kind Code:
B2
Abstract:
PURPOSE: To improve the adhesive properties with diazo photosensitive paint and the scratch resistance by sequentially providing a low crystalline resin layer and an aqueous resin layer at least on one side surface of a base material film in a laminated film adapted as a base material film such as a magnetic recording material, various photographic materials, or a packaging material.
CONSTITUTION: This laminated film comprises a low crystalline resin layer and an aqueous resin layer sequentially provided at least on one side surface of a base material film, wherein polymer containing ethylene phthalate or ethylene-2,6-naphthalate as main component is used as the base material film. As the resin, isophthalate copolymer polyester, dimer acid copolymer polyester, succinate copolymer polyester, or blends thereof are included, or preferably those in which the difference ΔTcg between the cold crystallizing temperature and the glass transition temperature of the polymer is 80°C or more are used. The resin layer is formed of acrylic copolymer having a functional group.
