ADHESIVE COMPOSITION AND LAMINATE USING THE SAME, AND SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition which has high adhesive strength in the adhesion of a thermal adhesiveness film and a metal foil, and can form a laminate that can maintain the high level of the adhesive strength even if immersed in an electrolyte solution for a long period of time.

SOLUTION: The adhesive composition includes 20-90 wt.% of an elastomer (A) and 10-80 wt.% of a tackifier (B) based on 100 wt.% of the total of the carboxyl group-containing styrenic thermoplastic elastomer (A) and the tackifier (B), wherein the carboxyl group in the tackifier (B) is 0-8 moles based on one mole of the carboxyl group in the elastomer (A), and includes polycarbodiimide (C) by the range in which the carbodiimide group becomes 0.3-10 moles based on one mole of the total of the carboxyl group in the elastomer (A) and the carboxyl group in the tackifier (B).
