<P>PROBLEM TO BE SOLVED: To provide a non-chlorine-based resin composition having good adhesion to a highly rigid polypropylene base material. <P>SOLUTION: In the resin composition for a highly rigid polypropylene base material, the resin composition contains a block copolymer (C) comprising: a polymer block (A) mainly composed of an olefin-based monomer unit; and a polymer block (B) composed of 2-25 mol% of a vinyl monomer unit having a carboxy group and 98-75 mol% of another vinyl monomer unit copolymerizable with the vinyl monomer, wherein the weight ratio of the polymer block (A) to the polymer block (B), (A)/(B), is 70/30 to 40/60. <P>COPYRIGHT: (C)2013,JPO&INPIT |
