A process for producing an ozone-resistant flexoqraphic printing form based on a photopolymerizable elastomeric mixture is described, which comprises applying to a developed and optionally post-treated flexographic printing form a treatment reagent containing as the essential constituent at least one polyglycol ether of the general formula I ( I) in which R1 and R2 are alkyl, especially (C1-C3)-alkyl, R3 is hydrogen or alkyl, especially (C1 C3)-alkyl, A, B, C can be identical or different and are and D oxa-n- or -iso-alkylene, especially oxa n- Gr -iso-(C1-Cs)-alkylene and l+m+n+o is 3 to 40.
