The invention relates to a gas barrier composition as well as to compositenstructures having at least one surface of a molded resin coated with the composition, nsaid composition comprising:n (A) an alkoxysilyl functional polyamine compound, or a hydrolyzate thereof, saidnpolyamine compound having three or more amine groups, at least one nitrogen atom ofnsaid amine groups being bonded to a hydrogen atom and at least one nitrogen of saidnamine groups being bonded to an alkoxysilyl group expressed by the formulan ―W―SiR 2 3―f (OR 1 ) f nwherein R 1 is an alkyl group having 1 to 6 carbon atoms, R 2 is a monovalentnhydrocarbon group having 1 to 10 carbon atoms, W is a divalent hydrocarbon groupnhaving 2 to 10 carbon atoms, and f is an integer having a value of 1 to 3; and (B) an organic compound which is free of acrylic groups, said organic compoundnhaving an aromatic ring or an alicyclic hydrocarbon group and having per molecule atnleast two functional groups that are reactive with the amine groups, the alkoxy groups,nor both, of component A. |
