Procedure

603 g of anhydrous ethylacetate, 603 g of trimethylol propane, 133.5 g of dimethyl amino ethanol and 178.5 g of methyl diethanol amine are dissolved. Into this solution in a double wall flask there is added drop by drop a solution of 522 g of anhydrous ethylacetate and 1044 g of toluylene diisocyanate at 40° C., under thorough agitation and simultaneous cooling, over a period of 3 hours, wherein the temperature does not exceed 50° C. To complete the reaction, the mixture is then heated to 60° C. and after attaining a NCO proportion of 0% it is diluted with 490 g of ethylene glycol monoethyl ether. The ethylacetate is distilled off as completely as possible in vacuo at 60° C. and the product diluted with further 500 g of ethylene glycol monoethyl ether.
