Abstract
A two-part type adhesive composition which comprises a first composition comprising (A) a nitrile butadiene rubber having an acrylonitrile content of from 10 to 30%, (B) a polymerizable (meth)acrylic liquid composition, (C) an organic peroxide and (D) a basic compound having an amine structure, and a second composition comprising (E) a reaction condensate of an amine and an aldehyde and (F) a reducing agent containing copper, is provided. In a preferred embodiment, the first composition also contains a photopolymerization initiator. A bonding method using the adhesive composition provides high adhesion and quick curing properties on the second time scale, and a high retention in durability on a high temperature and high humidity test.
