PROBLEM TO BE SOLVED: To provide both a high solid content coating composition capable of forming a film having excellent finish appearance, a film hardness, acid rain and scuff resistance, etc., and provide method for forming a multilayered film using the composition. SOLUTION: This high solid content coating composition is characterized as comprising (A) a compound which is a reactional product of a carboxy group-containing compound with an epoxy group-containing compound and has <=1,000 weight-average molecular weight and 200-800 hydroxyl value, (B) a hydroxy group-containing resin having 500-6,000 weight-average molecular weight and 50-600 hydroxyl value, (C) a polyisocyanate compound, (D) a melamine resin and (E) an alkoxysilyl group-containing compound. The method for forming the multilayered film which is composed of >=1 layers of colored films and >=1 layers of transparent films is characterized by forming the topmost layer transparent film from the high solid content coating composition.
