ABSTRACT:
Described is a single component aqueous adhesive composition especially suitable for flexible printed circuits. The composition consists of water and a homogeneous film-forming acrylic polymer. The acrylic polymer is a polymerization product of (A) acrylonitrile or methacrylonitrile, or mixture thereof, (B) an alkyl acrylate or methacrylate having 1-12 carbon atoms in the alkyl group, or mixture thereof, (C) an oxirane-containing polymerizing ethylenic monomer and (D) a hydroxyl- or amide-containing acrylate or methacrylate.
The adhesive composition is useful for bonding metal foils to polyimide films in the manufacture of flexible printed circuits.
