ABSTRACT:
There is provided a coating material made of a saponification product of a modified ethylene-vinyl acetate copolymer containing a cross-linkable olefinically unsaturated monomer. The saponification product is characterized by its intrinsic viscosity not greater than 0.7 dl/g which is measured at 20.degree. C. using phenol containing 15 wt % of water as a solvent. This polymer is readily soluble in solvents, and the resulting solution can have concentration as high as 20 to 50 wt % and provide coating film which is as strong as that obtained from the conventional EVOH having a high degree of polymerization.
