Abstract: The invention relates to a reaction product UA of at least one cyclic urea U and at least one multifunctional aldehyde A which reaction product has as substituents on the carbonyl carbon atoms of the aldehyde A at least one kind of functional groups selected from the group consisting of hydroxyl groups -OH and alkoxy groups -OR characterised in that the groups - OR comprise at least two kinds of alkoxy groups -OR 1 and -OR 2 , where R 1 and R 2 are both selected from the group consisting of linear, branched or cyclic alkyl groups having from one to twelve carbon atoms, where R 1 and R 2 may be the same or may be different from each other, to a process of making these, and to a method of use as crosslinker in coating compositions.
