(57) [Summary] [Purpose] To obtain a coating agent having excellent adhesion to both a polyolefin-based substrate not treated with a chlorine-based solvent and a top coating, solvent resistance, and water resistance. [Structure] For a polyolefin-based molded product comprising a chlorinated product of a modified polyolefin obtained by reacting an acid-modified low-molecular-weight polyolefin with a low-molecular diol or a low-molecular compound having a hydroxyl group and an amino group in the molecule and a urethane resin Coating agent. [Effect] When used as a primer for a polyolefin-based molded product substrate that is not treated with a chlorine-based solvent, it is excellent in adhesion, solvent resistance, water resistance and the like. |
