A process for forming full color images using a photosensitive material which includes a support having a layer of photosensitive microcapsules on the surface thereof, said photosensitive microcapsules including a first, a second and a third set of microcapsules uniformly distributed on said surface; said first set of microcapsules contains a cyan image-forming agent and a first photohardenable composition sensitive in a first wavelength band, said second set of microcapsules containing a magenta image-forming agent and a second photohardenable composition sensitive in a second wavelength band, and said third set of microcapsules containing a yellow image-forming agent and a third photohardenable composition sensitive in a third wavelength band; said process comprising the steps of: uniformly exposing said photosensitive material to radiation within at least one of said first, second, and third wavelength bands in an amount sufficient to sequester oxygen present in said microcapsules and thereby adjust the gamma of at least one of said first, second and third sets of microcapsules such that it more closely approximates the gamma of the other of said microcapsules; image-wise exposing said photosensitive material to radiation within said first, second and third wavelength bands; and subjecting said microcapsules to a uniform rupturing force to cause said microcapsules to rupture and release image-wise said cyan, magenta and yellow image-forming agents.
