    摘要： The present invention relates to novel mono- or polynuclear melamine compounds and their use as dispersants for pigments and fillers in coating compositions, in particular in solvent-borne coating compositions. The mono- or polynuclear melamine compounds of the invention have at least one 2,4,6-triamino-1,3,5-triazine ring, wherein at least one amino groups of at least one of the 2,4,6-triamino-1,3,5-triazine rings of the mono- or polynuclear melamine compounds is of the formula A: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ NR 1 R 2 €ƒ€ƒ€ƒ€ƒ€ƒ(A) where R 1 is H, CH(R 3 )OR 4 or R2, R 2 is CH(R 3 )O(A-O) x -R 5 , where R 3 is H, C 1 -C 10 -alkyl or aryl; R 4 is H, C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl; R 5 is a hydrocarbon radical having from 1 to 40 carbon atoms; x is an integer from 2 to 500, having on average a value in the range from 2.5 to 400; A is an C 2 -C 4 -alkan-1,2-diyl radical.
