Document Type and Number:

Japanese Patent JP5527192

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide an adhesive composition formable of a laminate which has high adhesive strength in adhesion between a thermally fusible film and a metal foil, maintains adhesive strength at a high level even if immersed in an electrolyte solution and hardly softens and flows by heat which is produced when an adhesive layer bonding the thermally fusible film to the metal foil thermally fuses the thermally fusible film.SOLUTION: The adhesive composition includes 2-30 wt.% of a polyol (A) that is obtained by adding a polyalkylene oxide to a bisphenol compound and has a hydroxyl value of 100-450 mgKOH/g, 10-80 wt.% of a carboxy group-containing styrene-based thermoplastic elastomer (B) and 10-80 wt.% of a tackifier (C) in 100 wt.% of the total of the polyol (A), the elastomer (B) and the tackifier (C) and a polyisocyanate (D) in the ratio of the isocyanate of the polyisocyanate (D)/the hydroxy group of the diol (B) of 0.3 to 8/1 (molar ratio).
