摘要: ELECTROGRAPHIC PROCESS FOR MAKING TRANSPARENCIES Abstract of the Disclosure A transparency that is used to project an image onto a viewing surface such as screen prepared by electrographic copying process. An element in this process comprises trans-parent support coated with image-receiving hydrophilic colloid layer receives pattern fusible toner particles. The particles fused hydro-philic contacting toned image-bearing heated fuser roll. release liquid which inhibits offsetting surface. Transparencies exhibit good resistance abrasion areas while also displaying substantially no non-toned upon projection viewing. Furthermore, transparencies can be selectively removed light rubbing moist cloth or tissue.
