HYDROXY-RESINOUS BINDER MATERIALS CONTAINING BOUND AZO PHOTOSENSITIZER, METHOD AND USE

摘要

HYDROXY-RESINOUS BINDER MATERIALS CONTAINING BOUND AZO PHOTOSENSITIZER, METHOD AND USE A photosensitive alkali-soluble, thermally-stable fluorinated hydroxy-resinous polyamide or polyimide composition comprising a resin-bound diazo sensitizer incorporated by the reaction of a diazo sensitizer compound with a predetermined percentage of the hydroxy groups of the hydroxy-resin binder material. The present compositions are self-sensitized, have adjustable alkali-solubility and provide high speed photoresist compositions for producing relief patterns having good edge definition and high thermal stability.
