Patent ID: 11512199

Abstract:
The present invention provides a resin composition which is highly sensitive and exhibits high chemical resistance even in the case of being baked at a low temperature of 250° C. or less and can suppress the generation of outgas after curing. The present invention is a resin composition which contains (a) an alkali-soluble resin containing polyimide, polybenzoxazole, polyamide-imide, a precursor of any one of these compounds and/or a copolymer of these compounds and (b) an alkali-soluble resin having a monovalent or divalent group represented by the following general formula (1) in a structural unit and in which the modification rate of a phenolic hydroxyl group in the alkali-soluble resin (b) is 5% to 50%. (In general formula (1), O represents an oxygen atom. R1 represents a hydrogen atom or a hydrocarbon group which has 1 to 20 carbon atoms and may be substituted and R2 represents an alkyl group having 1 to 5 carbon atoms. s and t each independently represent an integer from 0 to 3. Provided that (s+t)≥1. d represents an integer from 0 to 2. u represents an integer from 1 to 2, and * represents a chemical bond.)
