Abstract
A photosensitivematerial including a support having a layer of photosensitive microcapsules on the surface thereof, the photosensitive microcapsules including an internal phase containing a photosensitive composition and a color precursor wherein, upon image-wise exposing the photosensitive material and rupturing the microcapsules, the color precursor is image-wise released from the microcapsules to form a color image, the photosensitive material further including a superabsorbent polymer or hydrogel, is disclosed.
