PROBLEM TO BE SOLVED: To provide a hot-melt adhesive retaining its adhesive force and flexibility and having high heat resistance. SOLUTION: The hot-melt adhesive comprises (D) a copolymer with an aromatic vinyl monomer (d1), an aliphatic or alicyclic unsaturated hydrocarbon (d2) and/or a 4-24C alkyl or alkenyl (meth)acrylate (d3) as the essential constituent monomers and (E) a (co)polymer having a glass transition temperature (Tg) at least 10°C higher than that of the copolymer D and having an aromatic ring-containing monomer as the essential constituent monomer. The hot-melt adhesive has a melt viscosity (Pa.s; JIS K7117-1987) of 6.1-100 at 140°C. COPYRIGHT: (C)2004,JPO
