Abstract
A method for forming a full color photosensitive material in a single batch and the material produced thereby is disclosed. The method includes dispersing three internal phases, each containing a different color-forming agent in a continuous solution to form an emulsion, and thereafter forming mirocapsule walls around each of the internal phases. The invention is particularly characterized by the use of an agent to control intermixing of the internal phases.
