The invention relates to the use of pigment preparations comprising C.I. Pigment Yellow 74 as base pigment and one or more pigment dispersants of the formula (I) ##STR00001## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and R.sup.6 independently represent hydrogen, halogen, such as chlorine or bromine, C.sub.1-C.sub.4 alkyl, such as methyl, ethyl or tert-butyl, C.sub.1-C.sub.4 alkoxy, such as methoxy or ethoxy, nitro, trifluoromethyl, cyano, phenyl, a group SO.sub.3.sup.-E.sup.+- or COO.sup.-E.sup.+, provided that there is at least one and no more than two ionic groups of type SO.sub.3.sup.-E.sup.+- or COO.sup.-E.sup.+ are supplied, one group being located in the coupling radical and the other being located in the base radical of the compound of the formula (I) in case two ionic groups are supplied, E.sup.+ represents H.sup.+, the equivalent M.sup.m+/m of a metal cation M.sup.m+, m representing one of the numbers 1, 2, or 3 a phosphonium ion; or an unsubstituted or substituted ammonium ion, for pigmenting electrophotographic toners and developers, inks, aqueous binder systems, and color filters.
