Zusammenfassung: | PURPOSE:To provide an adhesive compsn. having excellent heat resistance and flexibility and suitable for use in the production of flexible printed circuit boards, by blending a modified epichlorohydrin rubber, an acrylic compd. and a polymn. initiator. CONSTITUTION:10-95wt% alkyl glycidyl ether copolymerized-modified epichlorohydrin rubber (A) such as Zechlon 1,100, 90-5wt% acrylic compd. (B) such as (meth)acrylic acid or 2-hydroxyethyl (meth)acrylate and 0.1-5pts.wt.
