摘要：
The present invention provides a coating material composition with a gas-barrier property which comprises, as essential components, an ethylene-vinyl alcohol copolymer (A) obtained by saponifying an ethylene-vinyl acetate copolymer, an inorganic layered compound (B) and a solvent, wherein the total amount of (A) and (B) is 1 to 30% by mass and the mass ratio (A)/(B) is (30/70) to (50/50). The coating material provides gas-barrier properties to packaging materials.
