HYDROXY RESIN BINDER MATERIAL CONTAINING BOUND AZO PHOTO SENSITIZING AGENT AND MAKING AND USE THEREOF

摘要

PURPOSE: To obtain a photosensitive compsn. to form a uniform pattern having excellent resolution and adhesion by allowing a specified hydroxy group to react with an azoquinone sulfonyl chloride photosensitizer. CONSTITUTION: This photosensitive compsn. consists of a hydroxylated aromatic polyamide polymer or hydroxylated aromatic polyimide polymer having lots of radical hydroxyl groups and usually having high solubility with the solvent of a water-based alkali developer. The compsn. is produced by allowing hydroxyl groups by a specified proportion of the polymer to react with an azoquinone sulfonyl chloride photosensitizer to bond the sensitizer to the polymer. Thereby, with the obtd. photosensitive compsn., a uniform pattern having excellent resolution and adhesion can be obtd.
