INORGANIC SUBSTRATE COATED WITH UNDERCOATING

摘要

PROBLEM TO BE SOLVED: To provide layered undercoatings as an undercoating film on an inorganic substrate with a high water penetration resistance, a moisture- impermeable property and a high adhesion strength to a top coat. SOLUTION: A vinyl resin coating (A), a vinylidene halide type resin coating (B), and a vinyl resin type coating (C) are successively layered as undercoatings on the surface of an inorganic substrate to give an undercoating-bearing inorganic substrate.
