Title:
GAS BARRIER FILM AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3772490
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a film, which has gas barrier properties even under highly humid state and, at the same time, keeps the adhesion between the film and a base material and the gas barrier properties even after the lamination of the film to the base material by a method wherein an amine compound represented by a specified formula is included in a coating film.
SOLUTION: A gas barrier film is produced by forming a coating film, which is mainly made of inorganic laminar compound and water-soluble polymer and includes an amine compound represented by a formula, where R1 is hydrogen, 1-6C alkyl chain or its substitution product, aryl chain or its substitution product, R2 is hydrogen, 1C or more alkyl chain or its substitution product, aryl chain or its substitution product and R3 is 1C or more alkyl chain or its substitution product, aryl chain or its substitution product. In order to form a coating film onto a thermoplastic resin base material, the coating film is formed out of a dispersion prepared by dispersing the constituent components of the coating film in various solutions by gravure coating and then dried by a heat roll contacting method or the like in order to obtain the desired coating film.
