Abstract

Provided are a coating material that is for undercoating for a thin inorganic film, has excellent adhesiveness to various base materials, and produces no appearance change or no peeling off even under high-temperature conditions, and an acrylic-modified alkyd resin as a raw material for such a coating material. The acrylic-modified alkyd resin includes a copolymer including as essential components: an alkyd resin (A) having an unsaturated bond in a molecular structure; and a polymerizable monomer (B) having an unsaturated bond in a molecular structure. Also provided are a curable composition, a coating material for undercoating for a thin inorganic film, and a molded body including an undercoat layer including the coating material for undercoating for a thin inorganic film.
