ABSTRACT:
The invention relates to a photocurable, negative-working mixture and a recording material which is obtained therefrom and which is suitable for the production of elastic relief printing plates. The mixture contains a) an amphiphilic elastomeric binder, b) a free-radical-polymerizable compound which is compatible with the binder and which has at least one terminal, ethylenically unsaturated group and a boiling point of over about 100.degree. C. at normal pressure and c) a compound or a combination of compounds which is capable of initiating the polymerization of the compound b) on exposure to actinic light. The binder is made up of the segments A, B, C and X, where:
