Abstract

The present disclosure provides a jet-black multilayer coating film having excellent properties in high appearance, water resistance, and humidity resistance and comprising a base coating film and a clear coating film formed by a coating composition containing a plant-derived aliphatic polyester mainly and a method for forming the same. A jet-black multilayer coating film comprising a base coating film layer formed by a base coating composition which contains a polyester polyol (A-1) containing a polyol having three or more functions and lactic acid as a consisting component of 80 mol % or more and having a hydroxyl value of 140 to 240 mgKOH/g wherein 70 mol % or more of the hydroxyl groups are secondary hydroxyl groups, an acrylic resin (A-2) with a hydroxyl value of 30 to 80 mgKOH/g and a glass transition point of 40 to 80° C., and a polyisocyanate (A-3), and a clear coating film layer formed on said base coating film layer by a clear coating composition which contains a polyester polyol (B-1) obtained by polymerization of a raw composition of a polyol having three or more functions, sebacic acid, and a diol and having a hydroxyl value of 140 to 240 mgKOH/g, an acrylic resin (B-2) with a hydroxyl value of 120 to 220 mgKOH/g, and a polyisocyanate (B-3).
