The pigment preparations contain a) a finely divided pigment, b) at least one colourant containing at least one external basic group, c) at least one acidic and/or neutral phosphoric acid ester and d) optionally further assistants which are conventional in preparations of this type. The preparations are used for pigmenting printing inks and surface coatings (paints). The printing inks, pastes and surface coatings prepared using the preparations have significantly better flow properties than the inks and coatings obtained using pigments of the prior art.
