Abstract

A photosensitive recording element possessing a photosensitive recording layer which is applied to a dimensionally stable base, if desired on top of one or more intermediate layers, and has good photochemical properties and a long shelf life contains special sulfo-containing azo or azoxy dyes for controlling the photochemical properties in the photosensitive recording layer and/or in any intermediate layer present. Dyes which are suitable for use according to the invention can be obtained, for example, by autocondensation of 5-nitro-o-toluenesulfonic acid.
