ABSTRACT:
Pigment formulations contain a) a finely divided pigment, b) at least one colorant which has at least one external basic group, c) at least one acidic and/or neutral phosphoric ester and d) if required, further assistants conventionally used in such formulations. The formulations are used for pigmenting printing inks and lakes.
The printing inks, pastes and lakes produced using the formulations have substantially better flow behavior than the inks and lakes obtained using prior art pigments.
