    摘要: A photoimageable, aqueous acid soluble polyimide polymer comprising an anhydride, including a substituted benzophenone nucleus, a diamine reacted with the anhydride to form a photosensitive polymer intermediate, and at least 60 Mole % of solubilizing amine reacted with the photosensitive polymer intermediate to form the photoimageable, aqueous acid soluble polyimide polymer. An emulsion for electrophoretic deposition of a coating of a photoimageable, aqueous acid soluble polyimide polymer comprises a dispersed phase, including the photoimageable aqueous acid soluble polyimide polymer, dissolved in an organic solvent and a dispersion phase including a coalescence promoter and water. The emulsion may be applied, by electrophoretic deposition, to a conductive structure to provide a photoimageable coating on the conductive structure. After exposing the coating to a pattern of radiation for photocrosslinking exposed parts of the photoimageable aqueous acid soluble polyimide polymer, an aqueous acid developer solution removes unexposed photoimageable aqueous acid soluble polyimide polymer to reveal a crosslinked polyimide polymer image of the radiation pattern.

    摘要: The disclosure describes a multilayer article of manufacture comprising a substrate having adhered to it a terminally unsaturated adhesive polyimide, where the surface of the adhesive opposite the substrate is adhered to a polyimide, the article further characterized in having one set or a plurality of alternating layers of the terminally unsaturated adhesive polyimide and the polyimide. the bonding operation.A novel adhesive polyimide is also described which is an adhesive polyimide such as ODPA-APB terminated with unsaturated heterocyclic monoamines such as azaadenines, aminobenzotriazoles, aminopurines or aminopyrazolopyrimidines and optionally anhydrides, aminoacetylenes, vinylamines or amino phosphines. The novel polyimide may also contain unsaturated heterocyclic groups in the polymer backbone or chain, either as a partial or complete replacement for the aromatic diamines used in synthesizing the polyimide. This novel adhesive polyimide in this invention acts as an adhesive layer for the polymer-substrate (copper, polymer, glass ceramic) interface as well as a copper diffusion barrier layer for the polymer copper interface.
