Abstract

Radiation-curable formulations based on ethylenically unsaturated prepolymers and difunctional esters of ethylenically unsaturated carboxylic acids with diols having a linear alkylene chain of 7 to 14 carbon atoms, a process for coating substrates using these radiation-curable formulations, and their use as automotive topcoats.
