Coinitiator systems for photopolymerization of photopolymerizable compounds containing olefinic unsaturation are described. Such systems comprise (A) either a combination of at least one coumarin photoinitiator and at least one coinitiator compound which is a hydrogen atom donating coinitiator or an electron donating coinitiator, or at least one coumarin photoinitiator having in its molecular structure at least one photosensitizing amino group; and (B) at least one compound containing at least one maleimide or maleic anhydride derivative. Photopolymerizable compositions which comprise, in addition to such a coinitiator system, at least one photopolymerizable compound containing olefinic unsaturation are also described.
