(57) Abstract: In a method for coating a polyolefin coating object by a two-coat method, the smoothness, image clarity, weather resistance, water resistance, interlayer adhesion, cohesive failure resistance, metallic feel of a coating film, Improves gloss, etc., and further disperses the pigment of the base coat composition, Improving compatibility and storage stability. SOLUTION: The polyolefin coating object contains chlorinated polyolefin (a-1), hydroxyl group-containing resin (a-2) and cellulose acetate butyrate (a-3) as main components, A base coat composition (A) containing no cross-linking agent is applied, and then a hydroxyl group-containing resin (b-1), a polyisocyanate compound (b-2), a benzotriazole-based ultraviolet absorber and an oxalic acid anilide system are applied to the coated surface. A cross-linking curable clear coat composition (B) containing an ultraviolet absorber (b-3) as a main component, which is composed of an ultraviolet absorber, is applied, and the polyisocyanate compound (b- in the clear coat composition (B) is applied. A method for coating a polyolefin article, characterized in that both coatings are simultaneously crosslinked and cured according to 2). |
