ABSTRACT:
A method for the production of an aqueous dispersion of a water insoluble N-substituted N',N'-alkylene urea having the general formula I: ##STR1## wherein R.sup.1 denotes alkyl having 6 to 20 carbon atoms, phenyl or ##STR2## in case of m=1, or R.sup.1 denotes alkylene having 6 to 20 carbon atoms, phenylene or ##STR3## in case of m=2, where X denotes H, CH.sub.3 or OCH.sub.3 and n is 0 or 1, R.sup.2 denotes H or CH.sub.3, R.sup.3 denotes H, CH.sub.3 or C.sub.2 H.sub.5 and R.sup.4 denotes H or CH.sub.3, by the reaction of an alkylene imine having 2 to 4 carbon atoms with an isocyanate represented by the general formula II:
