GAS-BARRIER RESIN COMPOSITION, GAS-BARRIER COATING MATERIAL, AND GAS-BARRIER MOLDING

摘要

A gas-barrier resin composition comprising (A) 83 to 15 wt.% compound having two or more hydroxyl groups per molecule and (B) 17 to 85 wt.% compound which contains three or more successive carbon atoms in the molecule and has at least one carboxyl group bonded to each of the carbon atoms, wherein the compound (B) is either a compound having no anhydride structure between the carboxyl groups or a compound having at least one anhydride structure between two or more of the carboxyl groups; a gas-barrier coating material comprising the compound (A), the compound (B), and a solvent; and a gas-barrier molding formed from or with the composition or coating material. The molding has such high barrier properties that the molding suffers little decrease in gas-barrier properties even in a high-humidity atmosphere. It has excellent transparency and generates no harmful gases upon incineration. It is friendly to the natural environment because no organic solvent is used. It can be produced with satisfactory productivity.
