Abstract
Abstract Photoimageable polyquinoline compositions comprise a polyquinoline polymer, a diazonaphthoquinone and optionally a photosensitizer. The composition is prepared by dissolving the polyquinoline polymer, diazonaphthoquinone and photosensitizer in a solvent to form a solution, coating the solution onto a substrate and thereafter removing the solvent to form a film. The film is exposed to light through a photomask and developed by immersion in a selective solvent to yield a photopatterned dielectric film.
