Abstract

The present invention relates to a photosensitive recording material comprising a base, a photopolymerisable layer and a covering layer containing a mixture of at least one water-soluble or at least water-dispersible polymer and at least one additive, the additive being selected from the group consisting of alkoxylated alkylenediamines, alkoxylated (C10-C25) alkanols, phosphoric acid (C1-C15) alkyl esters and phosphoric acid (C1-C15) alkyl esters and the amount of the additive being in the range of 0.001 to 10.0% by weight, relative to the total weight of the non-volatile components of the covering layer. The present invention also relates to a process for preparing an offset printing plate with this recording material.
