Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for formation of a multilayer coating film which is excellent in adhesion to a coated matter and cold-resistant thermal load property.SOLUTION: A method for forming a coating film of two or more layers on a coated matter includes: a process in which a primer composition (A), which contains a hydroxyl group-containing acrylic resin (a1) of which a glass-transition temperature (Tg) is within a range of 50 to 100°C, is coated on the coated matter, thereby forming a coating film of a lower layer; and a process in which a top coat paint composition (B), which contains a hydroxyl group-containing acrylic resin (b1) of which a glass-transition temperature (Tg) is within a range of -20 to 50°C and a polyisocyanate compound (b2), is coated, thereby forming a coating film of an upper layer.SELECTED DRAWING: None 【課題】被塗物との密着性及び耐冷熱負荷性に優れた複層塗膜形成方法を提供すること。【解決手段】被塗物上に２層以上の塗膜を形成する複層塗膜形成方法であって、被塗物上にガラス転移温度（Ｔｇ）が５０〜１００℃の範囲内である水酸基含有アクリル樹脂（ａ１）を含有する下塗り塗料組成物（Ａ）を塗装して下層の塗膜を形成する工程、ならびにガラス転移温度（Ｔｇ）が−２０〜５０℃の範囲内である水酸基含有アクリル樹脂（ｂ１）及びポリイソシアネート化合物（ｂ２）を含有する上塗り塗料組成物（Ｂ）を塗装して上層の塗膜を形成する工程、を含む複層塗膜形成方法。【選択図】なし
