ABSTRACT:
A photo-curing composition including an image forming material, an ethylenically unsaturated monomer which is curable by polymerization thereof, a polymerization initiator which initiates the polymerization of the monomer, and two or more photosensitizers each of which absorbs a light and thereby causes the polymerization initiator to initiate the polymerization of the monomer, the photosensitizers having different maximum absorption wavelengths, respectively. A photosensitive capsule including a core material including the photo-curing composition, and a shell material within which the core material is encapsulated.
