The invention relates to a gas barrier composition as well as to composite structures having at least one surface of a molded resin coated with the composition, said composition comprising: (A) an alkoxysilyl functional polyamine compound, or a hydrolyzate thereof, said polyamine compound having three or more amine groups, at least one nitrogen atom of said amine groups being bonded to a hydrogen atom and at least one nitrogen of said amine groups being bonded to an alkoxysilyl group expressed by the formula-W-SiR23-f(OR1)f wherein R1 is an alkyl group having 1 to 6 carbon atoms, R2 is a monovalent hydrocarbon group having 1 to 10 carbon atoms, W is a divalent hydrocarbon group having 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 compound having an aromatic ring or an alicyclic hydrocarbon group and having per molecule at least two functional groups that are reactive with the amine groups, the alkoxy groups, or both, of component A.
