Abstract

Photosensitive recording elements which possess a photosensitive recording layer which is applied to a dimensionally stable base, if necessary via one or more intermediate layers, and have good photochemical properties and a long shelf life contain a compound of the general formula (I) ##STR1## where M is a hydrogen atom or proton, an alkali metal cation, the ammonium cation or an amine cation and R.sup.1 and R.sup.2 are identical or different and are each a substituted s-triazine ring, in the photosensitive recording layer and/or any intermediate layer present, in order to control the photochemical properties.
