Abstract
Provided is a gas-barriering coated film obtained by coating a gas barriering layer on at least one face of a flexible film or an inorganic-deposited polymer film, wherein the above gas-barriering layer is a polyurethane resin-cured material formed from a composition comprising an active hydrogen-containing compound (A) and an organic polyisocyanate compound (B), and 20% by weight or more of a skeletal structure represented by Formula (1) is contained in the above resin-cured material. The gas-barriering coated film of the present invention is excellent in various performances such as a layer-to-layer adhesive property, a gas barriering property at a high humidity, a bending resistance and a retort treating resistance in addition to a high gas barriering property, and therefore it is applied to various uses including packing materials for food and medicines to which a high gas barriering property is required.
