Abstract: The invention relates to transparent, undiscolored and uncrosslinked, radiation-curable binders of low additive content, obtainable by polymer-analogous reaction of epoxy-functional (meth)acrylate copolymers (A) with an unsaturated monocarboxylic acid (B), the reaction a) of the copolymer (A) taking place with at least 2 equivalents of the carboxylic acid (B), b) in the absence of reaction accelerators and inhibitors, c) in a continuously operated reactor, d) without solvent, e) at from 130 to 170° C., f) with a degree of conversion of at least 90% within an average residence time which is as short as possible but sufficient, and which is below 13 to 22 minutes. The reaction products contain virtually no byproducts and are advantageous binders for clearcoat materials and powder coating materials.
