Abstract
Curable coating compositions which contain, as the binder, one or more olefinically unsaturated compounds containing urethane groups, with or without one or more olefinically unsaturated compounds copolymerizable therewith, in which the olefinically unsaturated compound containing urethane groups is a reaction product of vinyl isocyanate and a compound which contains at least one hydroxyl group and at least one radical of an ester of an .alpha.,.beta.-olefinically unsaturated carboxylic acid of 3 to 6 carbon atoms. The compositions may, for example, be used for the manufacture of coatings which can be cured with electron beams.
Claims9
A radiation-curable binder for coating compositions which binder comprises one or more olefinically unsaturated compounds of the general formula (I) ##STR4## where x and y may be identical or different and each is a number from 1 to 5, R is hydrogen or methyl, R' is a divalent linear or branched radical of 2 to 16 carbon atoms which may or may not contain oxa groups, or is a divalent cycloaliphatic radical of 5 to 12 carbon atoms, R" is a divalent linear or branched aliphatic, cycloaliphatic or aromatic radical of 6 to 15 carbon atoms and R'" is a radical which is derived from a polyhydric alcohol, a polyether-ol or a polyester-ol and which has a valency corresponding to the sum of x+y, with or without additional other radiation-curable olefinically unsaturated compounds having acrylyl radicals.
