Abstract

The present invention relates to a process for the production of radiation-cured foams, characterized in that the radiation-cured foams are produced by 1) foaming of an aqueous composition A), 2) thermal drying of the foam produced from step 1), 3) curing of the foam by actinic radiation, the radiation-curable aqueous compositions A), the radiation-cured foams produced by the process according to the invention and the use of the radiation-cured foams for coating substrates.
