Abstract:
A photosensitive material comprising a support having a layer of microcapsules on one surface thereof, and microcapsules having an internal phase including a photohardenable composition, said composition comprising a free radical addition polymerizable or crosslinkable compound, a photoinitiator, and a color-forming agent, said microcapsules including a first set of microcapsules containing a cyan color-forming agent, a second set of microcapsules containing a magenta color-forming agent and a third set of microcapsules containing a yellow color-forming agent, at least one of said first, second and third sets of microcapsules containing a complex of an infrared sensitive cationic dye and a boranyl anion capable of absorbing infrared radiation and producing free radicals which initiate free radical polymerization or crosslinking of said polymerizable or crosslinkable compound and wherein the other sets of microcapsules are sensitive to visible or ultraviolet radiation.
