Abstract
Means are provided for preventing image diffusion in images formed by imagewise exposure of a microencapsulated photosensitive material to actinic radiation, followed by a color forming reaction between a chromogenic material and a developer. A curing agent for the photosensitive composition, such as an organic peroxide, is microencapsulated separately from the photosensitive material and included in the coating. When the capsules are ruptured, the released curing agent reacts with the photosensitive material and thereby stabilizes the formed color so that its quality will not deteriorate over time.
