Abstract
Isocyanate-modified compounds consisting of the reaction products of an organic isocyanate with compounds with multiple acrylic radicals, the average composition of which has the general formula: EQU X--Y--(Z).sub.m-p-1 ].sub.n wherein PA1 X is the radical derived by removing the OH groups from the carboxyl groups of an organic carboxylic acid containing n COOH groups and the number of carbon atoms of which is between 14 and 90, PA1 Y is the radical derived by removing m-p hydrogen atoms from the hydroxyl groups of an organic compound containing m OH groups, PA1 Z is the monovalent radical derived by removing the OH group from the carboxyl group of a monocarboxylic acid having at least one terminal CH.sub.2 .dbd.CH--COO-- radical, PA1 n is a whole number from 1 to 6, PA1 m is a whole number from 2 to 8, and PA1 p is a number of from 0 to 2.5 and greater than 0 With the proviso that m-p-1 is a positive number different from zero and that n(m-p-1) is between 2 and 15, processes for the preparation thereof, and compositions of matter, in particular UV inks or varnishes, comprising said compounds.
