A stable dispersion of an aminoplast which is obtained by a process which comprises condensing ammonia hydrazine or an organic compound having a molecular weight of from about 50 to about 400 and which contains at least two groups selected from the group consisting of -NH2 and -NH- with benzoquinone or a compound of the formula R-CO-R' in which R and R' stand for the same or different radicals selected from the group consisting of hydrogen C1-C4 alkyl groups which may carry chlorine substituents, C2-C4-alkenyl groups, C6-C10 aryl groups, C7-C10 aralkyl groups, C5-C10 cycloalkyl group and semi-acetals obtained by reacting said carbonyl compounds with monohydric or dihydric aliphatic alcohols having one to ten carbon atoms in an organic polyhydroxyl compound having a molecular weight of from about 250 to about 14000 as the reaction medium.
