The present invention relates to a process for the preparation of amine-modified epoxy (meth)acrylates by reacting organic compounds having epoxy groups with a) acrylic and/or methacrylic acid in a carboxyl/epoxide equivalent ratio of 0.8:1 to 0.99:1 and b) basic nitrogen compounds selected from ammonia and (cyclo)aliphatic primary or secondary amines in an NH/epoxide equivalent ratio of 0.01:1 to 0.2:1, such that the epoxy groups originally present are substantially completely reacted and at least 0.01 NH equivalents, per epoxide equivalent, of the basic nitrogen compounds are reacted with the epoxy groups still present after completion of the reaction according to step a). A present invention also relates to the use of the amine-modified epoxy (meth)acrylates obtained from this process as binders in radical- cured coating, putty or sealant compositions or for the preparation of molded articles.
