Beschreibung
Zusammenfassung:	An object of the present invention is to provide an active energy ray curable resin composition which gives a cured film excellent in heat resistance, thermal decomposition resistance and developability. A reactive polycarboxylic acid compound (A) is obtained by reacting a reactive epoxy carboxylate compound (c) with a polybasic acid anhydride (d) represented by the following formula (2) or formula (3). The reactive epoxy carboxylate compound (c) is obtained by reacting an epoxy resin (a) represented by the following formula (1) with a carboxylic acid compound (b) having both polymerizable ethylenically unsaturated group(s) and carboxyl group(s) in one molecule. (wherein, n represents an average value and represents a value of 0 to 20) (in the formula (2), R1 represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms).
