Abstract

Disclosed herein is an adhesive composition for an insulator, the adhesive composition including a copolymer formed by using at least one type of phenol-based monomer; at least one type of monomer that is polymerizable by an alkali salt; and at least one type of monomer that is polymerizable by a bisulfate.

First claim

The invention claimed is:
