Zusammenfassung:	The present invention relates to pyrrolopyrrole derivatives of the formula (I) (I) wherein A and B are identical or different aryl radicals, and DPP is a diaryldiketopyrrolopyrrole radical; which diketopyrrolopyrrole derivative is substituted by from 0 to 6 moles of -SO3M per mole of the pyrrolopyrrole derivative; wherein M is hydrogen or a metal or ammonium cation. The pyrrolopyrrole derivatives of formula I are useful as rheology-improving agents for pigment dispersions.
