An object of the present invention is to form a coating film having excellent storage stability as a one-pack type paint and having excellent dryness, finish, pencil hardness, scratch resistance, adhesion, alkali resistance, solvent resistance, and weather resistance. Provided are a starch-based coating composition and a coated article coated with the starch-based coating composition. SOLUTION Starch and / or modified starch (A), and product (B) having an isocyanate group obtained by reacting polyisocyanate compound (b1) and polyhydric alcohol (b2), or these And a resin obtained by radical polymerization reaction of a mixture of an aromatic radical polymerizable unsaturated monomer, a hydroxyl group-containing radical polymerizable unsaturated monomer, and optionally other radical polymerizable unsaturated monomer. A starch-based coating composition containing a resin composition obtained by reaction as a binder is used. [Selection figure] None |
