ることはできなかった。2. Description of the Related Art A polypropylene film mainly composed of polypropylene, a polypropylene copolymer or a mixture thereof is widely used as a packaging film because of its excellent mechanical strength and transparency.
On the other hand, it is known that a coating film provided on a polypropylene film surface in order to have functions such as gas barrier properties, heat sealing properties, and printability has poor adhesion. This is due to insufficient adhesion of the polypropylene film. To remedy this drawback, it has been proposed to provide various anchor layers between the coating and the polypropylene film. Japanese Patent Publication No. 45-32360 discloses the use of polyethyleneimine and a glycidyl-based epoxy resin for the anchor layer to improve the adhesion of the vinylidene chloride layer provided for the purpose of providing gas barrier properties. U.S. Pat. No. 3,023,126 discloses the use of an anchor layer containing isocyanate as a component. However, in these methods, not only the adhesion to the polyolefin film is not sufficient, but also it was not possible to print with UV ink or the like using only the anchor layer.

This film is stretched 5 times in the machine direction, and one surface of the machine film is corona-treated by a spark gap method (Corona treatment machine manufactured by Tomoe Kogyo Co., Ltd., processing power = 1.2 KW), and the wet tension of this surface is 40 dyne / cm. Was obtained. A modified layer 1 (concentration: 15%) mainly containing an aqueous dispersion of an ethylene copolymer of the obtained film was applied by a gravure method, dried, and then stretched 8 times in the transverse direction.
After the transverse stretching, a corona treatment was applied to the highly transparent easy-adhesion layer side (printed surface) to adjust the wetting tension to 46 dyne / cm. The final film thickness was 40 μm. Further, the coating amount of the modified layer after the transverse stretching was 0.1 g / m 2 . On the prepared surface-modified polypropylene film, the component of the anchor layer is represented by the coating material represented by the anchor layer 1 (concentration: 6%, solvent:
(Water / IPA) was applied at a coating amount of 0.3 g / m 2 and dried to obtain a highly transparent and easily adhesive film.
