Radiation curable binders obtained by reacting A) amine-formaldehyde condensates having a formaldehyde:amino group molar ratio of from 1:1 to 2:1 with B) at least monohydric esters of acrylic or methacrylic acid with polyalcohols containing from two to four alcoholic hydroxyl groups, using from 0.1 to 0.3 hydroxyl equivalents of component B) per methylol equivalent of component A), in the presence of strong acids. These binders are suitable for use in coating compositions. |
