摘要

PURPOSE: To obtain an adhesive composition comprising a vinyl chloride-based resin and a polyolefin having specific viscosity characteristics, and providing an adhesive layer capable of firmly and integrally bonding a vinyl chloride-based resin layer and a polyolefin layer to each other. CONSTITUTION: This adhesive composition comprises (A) 100 pts.wt. of a vinyl chloride-based resin and (B) 10-350 pts.wt. of a polyolefin with a complex dynamic viscosityη* of <=1.2×10<5> poise (pref. olefin-based thermoplastic elastomer), and pref. furthermore, (C) <=20 (pref. 0.1-20, more pref. 2-10) pts.wt. of a foaming agent. This composition can be easily made into an adhesive molded form, for example, by powder molding thereof. And a composite molded form where the above molded form lies integrally laminated with a vinyl chloride-based resin molded form (e.g. a powder-molded sheet obtained by powder molding of vinyl chloride-based resin powder) can also be obtained.
