A process for the aftertreatment of relief printing plates which are prepared by the imagewise photopolymerization of layers containing as the binders, block copolymers of conjugated dienes and vinylaromatics, and by liquid development of the unexposed and thus nonphotopolymerized parts of the layers, said process comprising the step of treating the surface of said relief printing plates with an aqueous solution of bromates, bromides and one or more acids selected from the group consisting of aliphatic di-, tri- and tetracarboxylic acids.
- 2. The process of claim 1, wherein the aqueous solution contains one or more of succinic, glutaric and adipic acids.
- 3. A storable composition for use in the aftertreatment of relief printing plates containing one or more block copolymers of conjugated dienes and vinyl-aromatics in the relief layer, which composition can be activated by the addition of water and which comprises: a mixture of one or more solid acids selected from the group consisting of aliphatic di-, tri- and tetracarboxylic acids and at least one solid alkali metal or alkaline earth metal bromate or bromide.
