Abstract

Radiation-curable binders which are obtained by reacting A) an amine/formaldehyde condensate having a molar ratio of formaldehyde to amino groups of from 1:1 to 2:1 with PA1 B) one or more esters, having a free hydroxyl group, of acrylic acid or of methacrylic acid with polyalcohols which contain from two to four alcoholic hydroxyl groups, from 0.1 to 0.3 hydroxyl equivalent of component B) being used per methylol equivalent of component A), in the presence of a strong acid are suitable for use in coating materials.
