Abstract: N,N',N''-tris-(2-hydroxyethyl)-melamine, if required, as a mixture with N-mono- and N,N'-bis-(2-hydroxyethyl)-melamine, is prepared by reacting melamine with ethanolamine in the presence of an acidic catalyst by a method in which the reaction is carried out at from 120 DEG to 250 DEG C. using an excess of ethanolamine, and the molar ratio of free ethanolamine to the sum of free and converted melamine is not permitted to fall below 4:1 during the entire reaction time, and the stated (2-hydroxyethyl)-melamines are used as modifiers in the prepartion of aminoplast resins which are suitable for laminating surfaces.
