PROBLEM TO BE SOLVED: To provide a top clear coating composition intended for 2-coat-1-bake coating finish and capable of forming coating film of high resistance to acid and scratch. SOLUTION: This top clear coating composition essentially comprises (A) an acrylic copolymer made from an alkoxysilane group-containing vinyl monomer, hydroxy-containing vinyl monomer or another vinyl monomer, (B) a low- molecular weight polyol having each specific hydroxy number and molecular weight distribution, (C) a non-aqueous dispersion-type acrylic resin and (D) an amino resin consisting of hexamethoxymethylmelamine and/or an etherified melamine resin where part or the whole of the methoxy groups in hexamethoxymethylmelamine are substituted with a >=4C alcohol.
