PURPOSE:To eliminate the transfer of silicone to a self-adhesive layer and to economically prepare a laminate in a relatively easy manner by laminating a polyolefinic resin having a side chain composed of polysiloxane and a thermoplastic resin and stretching the laminated one. CONSTITUTION:A laminate is formed by laminating a polyolefinic resin having a side chain composed of polysiloxane and a thermoplastic resin and stretching the laminated one. The polyolefinic resin having the side chaine composed of polysiloxane is a comb-shape polymer formed by bonding polysiloxane to an olefin homopolymer or copolymer as the side chain. As the olefin homopolymer, a homopolymer of alpha-olefin such as ethylene or propylene can be designated. As polysiloxane constituting the side chain of the polyolefinic resin, polydimethylsiloxane or polydiethylsiloxane is employed. |
