Abstract

A procedure for obtaining electrophotographic records in the form of reductions on a linear scale of 5: 1 and less, with a recording material based on a transparent and conductive carrier, or a transparent carrier provided with a conductive layer and a layer of one or more organic photoconductors, optionally mixed with sensitizers, incorporated into binders, the ratio of the weight of the binder corresponding to at least three times, preferably the fivefold weight ratio of the organic photoconductor material, with the conductive carrier possibly being provided with a drawing in color, by charging the photoconductive layer, photographic exposure and developing with colored and triboelectrically charged particles, characterized in that depending on the resolving power, the photoconductive layer is positively or negatively charged, the exposure being carried out in such a way that absorption of light from the photoconductive layer asci only a fraction of the maximum amount.
