A stable dispersion of an aminoplast which is obtained by a process which comprises condensing ammonia, hydrazine or a 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 --NH 2 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 C 1 -C 4 alkyl groups which may carry chlorine substituents, C 2 -C 4 -alkenyl groups, C 6 -C 10 aryl groups, C 7 -C 10 aralkyl groups, C 5 -C 10 cycloalkyl groups or 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. |
