Abstract
A capsular imaging system wherein the imaging material comprises a support coated on one surface with a layer of capsules containing, as an internal phase, a radiation sensitive composition and a decolorizing agent; images are formed by a dry process wherein the aforesaid sheet is image-wise exposed; exposure of the sheet controls release of the decolorizing agent from the capsules which image-wise reacts with a dye layer and causes a color change. Embodiments are also disclosed in which the decolorizing agent inhibits or reverses the color forming reaction between a dye precursor and a dye developer.
