PURPOSE:To obtain a molding by using a mixture of chlorinated olefin and polyurethane as an adhesive and free from release from an adherent also in case of using PVC, etc., as a molding substrate and a polyolefin as a tape joining to the back face of the substrate. CONSTITUTION:1-250pts.wt. polyurethane is mixed with 100pts.wt. chlorinated polyolefin normally in the presence of a solvent. Then, a tape 3 is jointed to the back face of a molding substrate 2, using said mixture as an adhesive to provide the aimed molding 1. The chlorinated polyolefin has preferably 5-60% chlorination degree. The same solvent as the solvent used for preparing polyurethane is preferably used as a solvent for preparing the adhesive. Examples of the solvent are preferably a mixed solvent of 1,1,1-trichloroethanol and dimethylsulfoxide, etc. |
