RADIATION SENSITIVE RESIN COMPOSITION

摘要

PURPOSE:To obtain the titled composition capable of forming a polyimide cured film having excellent heat-resisting and solvent-resisting properties by radiating the titled composition by comprising the composition of a solution which dissolves a specific polyimide and an aromatic bisazide compd. in a solvent so as to contain >=95wt% the total of the specific polyimide and the aromatic bisazide compd. on the weight basis of the solid contg. in said solution. CONSTITUTION:The titled composition is composed of the solution which dissolves the polyimide and the aromatic bisazide compd. in the solvent. Said polyimide and the aromatic bisazide compd. are obtd. by reacting an aliphatic tetracarboxylic acid or its anhydride and a diamine compd. or a diisocyanate compd. And, said solution contains >=95wt% the total of the polyimide and the aromatic bisazide compd. on the weight basis of the solid contd. in the solution. Thus, the titled composition capable of forming the polyimide cured film having excellent heat-resisting and solvent-resisting properties by radiating the radiation such as a visible ray is obtd.
