ABSTRACT:
The present invention provides a radical generator having a naphthalimide structure or a crosslinking agent and a photosensitive compound having a function as a radical generator. A photoradical polymerization initiator of the present invention comprises a compound (a) having only one naphthalimide structure-containing group in one molecule. The radial generator of the present invention comprises a compound (c) having two or more naphthalimide structure-containing groups in one molecule and also functions as a crosslinking agent. A first photosensitive compound of the present invention comprises a compound (d) having a naphthalimide structure-containing group and an ethylenic unsaturated group in one molecule. A second photosensitive compound of the present invention comprises a polymer (e) of one or more radical polymerizable compounds containing the compound (d). A photosensitive resin composition according to the present invention contains, as an essential component, the above compound (a), compound (c), compound (d) or polymer (e).
