The present invention provides a water-based coating 2 that is excellent in coating film performance, heat yellowing resistance and surface smoothness, and has excellent dispersion stability of a polyisocyanate compound, as a clear coating in a top coating of an automobile represented by 2-coat 1-bake metallic coating. To provide a liquid-type clear coating composition and a method for forming a multilayer coating film. A hydroxyl group-containing resin having a hydroxyl value of 30 to 200 mg KOH / g, an acid value of 5 to 50 mg KOH / g, a weight average molecular weight of 3000 to 30000, and a glass transition temperature in the range of −30 ° C. to 40 ° C. Aqueous two-component clear coating composition comprising hydroxyl group-containing resin particles (A) obtained by dispersing (a) in water and a hydrophilic polyisocyanate compound (B) having a phosphate group and a polyether group And multilayer coating film forming method using the same.
