Abstract: 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 gam
