Abstract
Abstract A METHOD OF RECORDING INFORMATION USING A RECORDING MATERIAL HAVING A WATER-PERMEABLE RECORDING LAYER CONSISTING ESSENTIALLY OF A CONTINUOUS PHASE OF AT LEAST ONE PROTEINACEOUS HYDROPHILIC COLLOID BINDER HAVING DISTRIBUTED THERETHROUGH FINELY DIVIDED PARTICLES OF A HYDROPHILIC INORGANIC PHOTOCONDUCTIVE COMPOUND IN ONE EMBOIDIMENT AND FINELY DIVIDED PARTICLES OF A NON-PHOTOCONDUCTIVE HYDROPHILIC PIGMENT, PLUS AN ORGANIC PHOTOCONDUCTIVE DYE, IN ANOTHER EMBODIMENT, WHEREIN THE RECORDING LAYER IS IMAGE-WISE EXPOSED TO ACTIVE ELECTROMAGNETIC RADIATION AND THEN DEVELOPED BY CONTACTING THE SAME WITH AN AQUEOUS LIQUID TO PRODUCE A VISBILE CHANGE IN THE RECORDING LAYER BY PENETRATION OR REMOVAL OF THE WATER-PERMEABLE UNEXPOSED REGIONS OF THE LAYER BY THE AQUEOUS LIQUID. THE RATIO BY WEIGHT OF HYDROPHILIC PARTICLES TO HYDROPHILIC COLLOID IS ABOUT 1:1 TO 5:1 AND THE PROPORTION OF THE ORGANIC PHOTOCONDUCTIVE DYE IS AT LEAST ABOUT 0.05% BY WEIGHT OF THE HYDROPHILIC NON-PHOTOCONDUCTIVE PARTICLES.
