Use of (meth) acrylsäureestern of Dimerdiolalkoxylaten as building blocks for radiation-curable coatings

The invention relates to acrylic or methacrylic acids of addition products with 1-80 mol ethylene oxide and/or propylene oxide on dimerdiols with a majority of 36-44 C atoms - especially those with a Draize index of less than 2.0 - which are highly suitable as constituents for radiation cured coatings.
