Acrylic-modified alkyd resin and coating material for priming for thin inorganic film

Provided are: a coating material for priming for thin inorganic films which has excellent adhesiveness to various bases and causes neither an appearance change nor peeling even under high-temperature conditions; and an acrylic-modified alkyd resin which is a raw material for the coating material. The acrylic-modified alkyd resin is characterized by being a copolymer obtained from an alkyd resin (A) having unsaturated bonds in the molecular structure and a polymerizable monomer (B) having an unsaturated bond in the molecular structure as essential constituent components. Also provided are a curable composition and a molded object including a primer layer obtained from the coating material for priming for thin inorganic films.
