Abstract
Abstract Novel dye salts of anionic dyes of the general formula I ##STR1## where F is a radical of an anionic dye, n is 1, 2, 3 or 4, and B 1 and B 2 independently of one another are each unsubstituted or substituted branched alkyl or alkyl-substituted cycloalkyl having a total of 10 to 36 carbon atoms, are very useful for dyeing solvents, printing inks or polymeric film-forming materials.
