An imaging system comprising a support having a layer of at least one set of photosensitive microcapsules on the surface thereof, wherein the microcapsules are sensitive to a distinct band of radiation and contain a complex of an infrared sensitive cationic dye and a boranyl anion. In a preferred embodiment, the photosensitive microcapsules include 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, wherein at least one of said first, second and third sets of microcapsules include an infrared sensitive dye borate compound as a photoinitiator. Optionally at least one other set may include a visible light sensitive dye borate compound or an ultraviolet initiator.
