ABSTRACT:
A photosensitive microcapsule which contains a polymerizable monomer and a polymerization initiator has increased sensitivity due to the displacement of soluble water in the monomer photosensitive microcapsule comprises a polymerizable monomer contained in a microcapsule; a photopolymerization initiator comprising a hydrophobic sensitizer for initiating polymerization of the polymerizable monomer in response to incident light energy; and an image producing material such as a dye or a precursor; wherein the hydrophobic sensitizer includes at least one of 3,7-bis (octadecylmethylamino) phenothiazoniumchloride which reacts on a red color light energy, 3,7-di(octadecylmethylamino)-5-phenylphenaziniumchloride which reacts on a green color light energy, and 3,6-di(octadecylmethylamino)-acridinechloride which reacts on a blue color light energy.
