Abstract

In June, 1977 a novel electrophotographic film -- known as KC-Film -- was introduced to the Graphic Arts Market. This film consists of a very thin layer (3000 Å thick) of wholly inorganic material sputtered onto a polyester substrate in a proprietary process. The tiny, vertical crystallites (700 Å diameter) function as anisotropic image receptors fea-turing extremely short response times, better than one nanosecond, and they display discharge levels proportional to the amount of absorbed energy. Accordingly, it is possible to digitally record pulses at great bandwidth as either binary or intermediate level signals without reciprocity failure and at theoretical resolution levels of 10,000 cycles/mm. These signals can be developed into visible images with electrostatic toner with great fidelity for storage, reprocessing, viewing, or even printing. With especially formulated toners it is possible to print the recording lithographically, i.e., with multiple colors, generating rather esoteric imagery. The daylight handling, infinite storage, and erasability features are expected to lead this recording material toward many applications in the laser, LED, or electron beam recording fields.
