  • Copper phthalocyanine photoreceptor and method for producing the same
    Patent number: 4882250
    Abstract: A photoreceptor comprises a conductive substrate, a charge generating layer and a charge transporting layer, the charge generating layer being formed by bonding to the substrate a film layer having a composition consisting of copper phthalocyanine and a binder and then exposing said bonded film to iodine vapor for 1-120 min at 20 deg C.-90 deg C. The charge transporting layer is formed of a binder and an organic compound selected from hydrazones, pyrazolines, oxazoles, thiazoles and triaryl methane.

  • Single component aqueous acrylic adhesive compositions for flexible printed circuits and laminates made therefrom
    Patent number: 4762747
    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.
