Abstract
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:NRR(A) where Ris H, CH(R)ORor R, Ris CH(R)O(A-O)—R, where Ris H, C-C-alkyl or aryl; Ris H, C-C-alkyl or C-C-alkoxy-C-C-alkyl; Ris 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-C-alkan-1,2-diyl radical.
