Patent ID: 8092917

Claim:
A printable gas-barrier laminate consisting of a plastic substrate (A), an inorganic film (B) having a thickness of 0.5 to 40 nm formed on at least one surface of the plastic substrate (A), and a polyester-based resin layer (C) having a thickness of 0.5 to 5 μm formed by applying on a surface of the inorganic film (B) a coating material containing a polyester-based resin, a fatty amide in an amount of 0.1 to 20 parts by weight based on 100 parts by weight of the polyester-based resin and a polyisocyanate as a curing agent in which a content of the polyisocyanate in the coating material is 0.8 to 1.5 times a hydroxyl equivalent of the polyester-based resin, said polyester-based resin having a glass transition temperature of 50 to 70° C., a weight average molecular weight of 1500 to 8000 and a hydroxyl value of 10 to 60 mg KOH/g, and said gas-barrier laminate having an oxygen permeability of not more than 5 cc/m 2 /day/atm and a water vapor permeability of not more than 5 g/m 2 /day.
