(57) Abstract: The present invention relates to a polyolefin (primer) for forming a coating film having excellent adhesion to a polyolefin (substrate) and an adjacent topcoat film, and a polyolefin molded article using the primer. Related to the painting method. The number average is obtained by polymerizing a monomer component containing 30 to 95% by weight of at least one selected from cyclohexyl acrylate, cyclohexyl methacrylate, isobutyl acrylate, isobutyl methacrylate, n-butyl acrylate and n-butyl methacrylate. A polyolefin primer comprising: an acrylic resin (A) having a molecular weight of 1,000 to 40,000 and a hydroxyl value of 10 to 200; and a chlorinated or non-chlorinated polyolefin (B). A method for coating a polyolefin, comprising applying the primer to a polyolefin and applying an overcoat containing a polyisocyanate compound to the uncured surface. |
