Abstract
An imaging sheet used for achieving color balance in a full-color imaging system is disclosed. The sheet is characterized by utilizing three sets of microcapsules, each containing a different colorless image-agent and a photohardenable or photosoftenable composition, and a corrective dye associated with the substrate. Association of the corrective dye with the substrate achieves color balance by equalizing the speed of the different colorless color-forming microcapsules.
