Abstract
A process for the preparation of melamine resin solutions modified by sulfites, by dissolving melamine in an aqueous formaldehyde solution at elevated temperature, cooling the solution, adding an alkaline sulfite, adjusting a ph value higher than 7, heating, returning to cooling, acidifying and condensing in the acid range and then adjusting a ph value higher than 7, characterized in that after dissolved melamine in a formaldehyde solution with a ph value of approximately 3.5 to 5, it is precondensed for 20 to 100 minutes at 75 to 85ºC and, after the acid condensation, the resin solution is heated, adjusted to a ph value of about 8 to 11, for 1 to 3 hours under reflux.
