Beschreibung
Zusammenfassung:	Provided is a curable resin composition having developability and resolution improved without degrading the heat resistance and the chemical resistance, furthermore, a curable resin composition that is useful as a PID material for optical uses or a material for optical sensor protective films and enables the formation of a cured product having both higher transparency and excellent heat resistance, a dry film containing the curable resin composition, a cured product thereof and a printed wiring board including the cured product. A curable resin composition containing (A) an amide-imide resin, (B) a compound having an ethylenic double bond and (C) a photopolymerization initiator, wherein the amide-imide resin (A) is a reaction product of an isocyanurate-type polyisocyanate synthesized from an isocyanate having an aliphatic structure and a tricarboxylic acid anhydride and has a number-average molecular weight of 500 to 1000.
