A photopolymerizable composition is herein provided and it comprises the following components: a) a photopolymerizable compound; b) a photopolymerization initiator; and c) organic pigment fine particles on which the polymer of a polymerizable compound is immobilized, whose volume average particle size: Mv is not more than 50 nm, and which has a ratio: Mv/Mn (wherein Mv represents the volume average particle size of the pigment fine particles and Mn represents the number average particle size thereof) ranging from 1 to 1.5. The photopolymerizable composition can be used in various applications such as the 3-dimensional optical moulding or holography, a plate material for forming lithographic printing plate, image-forming materials such as color proof, photoresists and color filters, ink and photocurable resin materials such as adhesives. More particularly, the photopolymerizable composition may be an actinic ray-curable ink jet recording ink composition, which is excellent in the curability and gloss and which can form images of high quality. |
