Document Type and Number:
WIPO Patent Application WO/2013/011825
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive composition which can be processed by a dry lamination method and which is applicable to battery packaging materials that are required to have excellent electrolyte solution resistance and excellent heat resistance.
The present invention relates to an adhesive composition for battery packaging materials, which contains (A) a reactive functional group-containing styrene elastomer that has at least one reactive functional group selected from the group consisting of a carboxyl group, an amino group and a hydroxyl group and (B) a compound that has two or more isocyanate groups in each molecule. The molar ratio of the isocyanate groups in the compound (B) that has two or more isocyanate groups in each molecule relative to the reactive functional groups in the reactive functional group-containing styrene elastomer (A) is preferably 0.5-10.0.
