Abstract

940,273. Electrophotographic reflex copying processes. KALLE A. G. Feb. 12, 1960 [Feb. 21, 1959], No. 5105/60. Heading G2H. [Also in Division H1] An electrophotographic reflex direct copying process comprises assembling together a master capable of reflecting light and transparent to translucent electrophotographic copy material comprising a support of sheet material and a photoconductive layer thereon, the layer being assembled on the side away from the master, charging, with substantial exclusion of light, the photoconductive layer before or after the assembly, passing light through the copy material and developing and fixing the resulting electrostatic copy image. In the case of translucent copy material, this may be made more transparent by soaking in a substance having a refractive index closer to that of the principal component of the support than in that of air.
