Procedure for the preparation of radiation-cured foams, characterized in that the radiation-cured foams are prepared by 1) in a first stage, foaming of an aqueous composition A), then 2) thermal drying of the foam prepared in stage 1), 3) curing the foam by actinic radiation or 1) in a first stage, foaming the aqueous composition A), then 2) curing the foam prepared in stage 1) by actinic radiation, 3) thermal drying of the foam, each of steps 2) and 3) can be repeated with any frequency, characterized in that the aqueous composition A) contains components A1) one or more radiation-curable aqueous binders, A2) one or more thickeners, A3) one or more foam stabilizers and characterized in that component A1) contains poly ((meth) acrylates of urethane) (i). |
