<P>PROBLEM TO BE SOLVED: To provide an adhesive composition which can form a laminate which has high adhesive strength in the adhesion of a heat sealing film and a metal foil, and can maintain the adhesive strength in a high level even if immersed in an electrolyte solution, and in which an adhesive layer which has adhered the heat sealing film and the metal foil hardly soften and flow with the heat at time of carrying out the thermal fusion of the heat sealing film. <P>SOLUTION: The adhesive composition includes the following (A)-(D): 10-80 wt.% of a carboxy group-containing styrenic thermoplastic elastomer (A); 2-30 wt.% of a diol (B) in which the hydroxyl value is 150-800 mgKOH/g, which is liquefied at 60°C, and whose components other than an hydroxy group in the structure consist of only a hydrocarbon component; 10-80 wt.% of a tackifier (C) based on 100 wt.% of the total of (A), (B), and (C), and further includes a polyisocyanate (D) in the range in which the isocyanate group of the polyisocyanate (D)/the hydroxy group of the diol (B)=0.3-8/1 (molar ratio). <P>COPYRIGHT: (C)2012,JPO&INPIT |
