To provide a polypropylene composition capable of giving a polypropylene molded article with improved adhesion by blending a modified polyethylene as an adhesiveness-imparting agent with a polypropylene and to provide a method for preparing a dichromatic molded article.

Preferably is further blended an acrylate compound bearing an aliphatic alkyl chain as an adhesiveness-imparting agent. The modified polyethylene is preferably a methyl acylate group-modified polyethylene, namely, a polyethylene with its hydrogens replaced partially, about 20-30%, by a methyl acrylate group. A modified polyethylene is preferably added in an amount of at least 5 pts.wt., based on 100 pts.wt. of polypropylene, more preferably in an amount of 10-30 pts.wt., whereby peeling strength is enhanced by a factor of at least about 2 to 3. By using this polypropylene composition and a thermoplastic elastomer composition, a molded body, comprising a molded body of the polypropylene composition and a molded body of the thermoplastic elastomer having adhered thereto, can be prepared.
