Abstract
A photosensitive resin composition which comprises (1) an ethylenically unsaturated compound which can be addition polymerized to form a high molecular compound, said addition polymerization being initiated by a free radical and chain-propagating, (2) a 2-polycyclic aryl-4,5-diphenylimidazolyl dimer wherein the polycyclic aryl group at the 2-position comprises at least two benzene rings condensed each other and (3) a heterocyclic mercaptan compound, said photosensitive resin composition being excellent in having a high photopolymerization initiation potency.
