<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable resin composition having excellent heat resistance, enabling the patterning with a diluted aqueous alkali solution, enabling a usual organic solvent to be used as a solvent, and capable of reducing a developing residue at alkali development. <P>SOLUTION: The active energy ray-curable resin composition contains: a branched polyimide resin (1) having a carboxy group and/or an acid anhydride group; a polymerizable resin (2) obtained by reacting an acid anhydride (2c) of a polycarboxylic acid having two or more carboxy groups with an esterified product of an epoxy compound (2a) and an unsaturated monocarboxylic acid (2b), and having the carboxy group; and an organic solvent (3). <P>COPYRIGHT: (C)2011,JPO&INPIT |
