Abstract
Abstract A light-sensitive composition which comprises at least one compound represented by the following general formula (I) as light-free radical generator: S-L-A (I) in formula (I), S represents a light absorbing moiety which absorbs light having a wave length of not less than 300 nm with an absorptivity coefficient of not less than 1000, A represents an active moiety which interacts with the light absorbing moiety S in an excited state to generate free radicals and L represents a group for coupling the moieties S and A; and a photopolymerizable composition which comprises at least one radical polymerizable compound having ethylenically unsaturated group, at least one compound represented by the foregoing general formula (I) as a light-free radical generator and optionally at least one linear organic high molecular weight polymer. The light-sensitive composition or the photo-polymerizable composition shows high sensitivity to actinic rays having a wave length ranging from near ultraviolet to visible region or further to near infrared region. Therefore, the composition can be imagewise exposed to light from a variety of light sources.
