To provide a coating composition suitable for forming a coating film excellent in gloss and polishability.

The coating composition comprises a hydroxy group-containing copolymer (A), a hydroxy group-containing copolymer (B), a cellulose derivative (C), and a polyisocyanate (D). The total amount of styrene (a) and a polymerizable unsaturated monomer (b) having a bridged alicyclic hydrocarbon group based on the total amount of monomer components composing the hydroxy group-containing copolymer (A) is 30 mass% or more. The total amount of styrene (a) and a polymerizable unsaturated monomer (b) having a bridged alicyclic hydrocarbon group based on the total amount of monomer components composing the hydroxy group-containing copolymer (B) is less 30 mass%.
