PURPOSE:To prevent an ink film from exfoliating or coming off during transportation or use, by providing a coated layer of a resin having a specified composition on a surface of a molded product of a polyolefin resin, and printing on the coated surface by using a printing ink. CONSTITUTION:A coating agent comprising a solution of 1-40wt% of a resin I and a resin II in a solvent is applied to a surface of a molded product of a polyolefin resin, in a dry basis coating weight of 0.1-40g/m<2>, followed by drying. Then, printing in a printing ink is performed on the coated surface. The resin I is obtained by radical polymerization of a block copolymer A such as a styrene-butadiene block copolymer with a radical-polymerizable monomer C in the presence of a graft-modified block copolymer B. The resin II is a mixture of the copolymer B with an acrylic resin obtained by radical polymerization of the monomer C. |
