<P>PROBLEM TO BE SOLVED: To provide a curable resin composition having good workability and superior developability and giving a cured product that can achieve good electric characteristics and reliability such as high moisture heat resistance, which are required when the composition is used for electronic parts or the like. <P>SOLUTION: The curable resin composition includes the following carboxyl group-containing photosensitive resin and a photopolymerization initiator. The photosensitive resin is obtained through steps of reacting a phenolic resin with an alkylene oxide or cyclocarbonate to obtain a reaction product, reacting the reaction product with an unsaturated group-containing monocarboxylic acid, and reacting the resultant reaction product with a polybasic acid anhydride. <P>COPYRIGHT: (C)2011,JPO&INPIT |
