This invention relates to a process to make a reaction product UA of at least one multifunctional aldehyde A with at least one cyclic urea U, by mixing the at least one multifunctional aldehyde A with the at least one cyclic urea U in the presence of at least one alcohol R&#x2014;OH, and optionally, at least one solvent that has no reactive groups which may react with aldehyde groups, &#x2014;CO&#x2014;NH&#x2014; groups, or hydroxyl groups, to effect an addition reaction to obtain a solution of a product UA, where Ris selected from the group consisting of linear, branched or cyclic alkyl groups having from one to twelve carbon atoms, to the reaction product obtained by this process, and to a method of use thereof as crosslinker for coating compositions.

Process for the preparation of a reaction product of a cyclic urea and a multifunctional aldehyde

Sulfonimide cure catalysts are used with aminoplast crosslinking agents and resins capable of reacting with aminoplast crosslinking agents to prepare heat curable compositions capable of crosslinking to form coatings and articles. Liquid or solid curable compositions may be prepared. Solid sulfonimide catalysts used in combination with solid glycoluril type crosslinking agents are well suited for powder coating systems containing hydroxy- and carboxy-functional resins.
