Beschreibung
Zusammenfassung:	In a hot melt adhesive comprising a thermoplastic block copolymer containing a block copolymer represented by formula (1) shown below (component A), tackifier (component B), diluent (component C) and stabilizer (component D), the content of component (A) is 10 to 40% by weight, the content of component (B) is 30 to 70% by weight, the content of component (C) is 30% by weight or less, and the content of component (D) is 0.1 to 4% by weight, all based on the total amount of said hot melt adhesive. A1-B-A2(1) wherein A1 and A2 are aromatic vinyl copolymer blocks having different molecular weights, and B is a conjugated diene polymer or hydrogenated derivative thereof; Accordingly, the hot melt adhesive described above not only fulfills the basic requirements such as adhesiveness to a polyolefin film, stability, holding ability and low cost, but also exhibits an excellent low temperature adhesiveness and satisfactory handling during spray coating process.
