Abstract
It is an object of the present invention to improve the curability of a resin composition and a photosensitive composition suitably employed to form e.g., a surface protecting film and an interlaminar insulating film of e.g., an electronic part, while reducing the internal stress remaining in a substrate when the composition is used to form a cured film on the substrate. The photosensitive composition includes a resin (A) having a phenolic hydroxyl group, a crosslinking agent (B1) having at least two oxazoline groups and a crosslinking agent (B2) having at least two groups represented by —CHOR (wherein R is a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an acetyl group) and a photosensitive acid-generating agent (C).
