The invention relates to an aqueous pigment preparation and to the use thereof for tinting systems and for dyeing coating substances, said aqueous pigment preparation comprising (A) at least one organic and/or inorganic pigment and/or filler, (B) at least one dispersant of the formula (I) or (II), or a mixture of dispersants of the formulae (I) and (II), where n is an integer greater than or equal to 1, z is an integer greater than or equal to 1, and n is an integer greater than or equal to 1. R1 is an aliphatic, linear or branched hydrocarbon residue having 1 to 30 carbon atoms or a hydrogen atom or a structural unit-O-X or a structural unit-CH2-O-X, and a structural unit X corresponding to formula (III) wherein a is an integer of 1 to 50, preferably 1 or 20, particularly preferably 1 to 10, b is an integer of 0 to 50, preferably 0 or 20, particularly preferably 0 to 10, c is an integer of 1 to 100, preferably 10 to 50, m is an integer of 1 to 50, preferably 1 to 10, and n is an integer of 1 to 30. R1 is an
