Abstract

988,229. Electrothermography. GEVAERT PHOTO-PRODUCTEN N.V. March 3,1961 [Dec. 4,1959], No. 48196/64. Divided out of and Addition to 988,228. Heading G2H. A latent electrostatic image is formed on an electrothermographic layer by a modification of the process of the parent Specification in which discharge of the uniform charge initially present on the layer is effected by infra red reflex contact printing exposure. The disclosure is otherwise substantially identical with that of the parent Specification. Specifications 782,165, 799,184, 819,592, 883,312, 891,781, 898,354, 901,605, 910,308, 916,660, 947,479, 964,871, 964,872, 964,875, 964,877, 964,879,and 975,813 also are referred to.
