Abstract

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