Abstract
The present invention relates to ethylenically unsaturated polyurethanes which PA1 i) are substantially free from isocyanate groups, PA1 ii) are liquid at 25.degree. C., PA1 iii) have a total content of ethylenically unsaturated groups (calculated as C=C, MW 24) of 1 to 20% by weight and PA1 iv) contain the reaction product of 4-isocyanatomethyl-1,8-octamethylene diisocyanate (NTI) with a hydroxyalkyl (meth)acrylate. The present invention also relates to a one-component coating composition containing these ethylenically unsaturated polyurethanes.
