Abstract
An imaging material and process employing photosensitive microcapsules useful in forming two or more image colors by exposure with an intensity or time modulated radiation source such as a laser; the imaging material comprises a support having at least two sets of photosensitive microcapsules on the surface, one set of microcapsules is made up of high speed microcapsules which are more sensitive to a predetermined actinic radiation than a second set of microcapsules made up of lower speed microcapsules; the microcapsules include a photosensitive composition which undergoes a change in viscosity upon exposure to actinic radiation; first and second image-forming agents are respectively associated with each set of microcapsules; the imaging material is useful in forming images of two or more colors by a process which comprises image-wise exposing the imaging material to actinic radiation at a first exposure amount which is substantially quantitatively different than the second exposure amount, and subjecting the exposed imaging material to a uniform rupturing force such as pressure.
