The present invention relates to solid pigment preparations containing (A) 5 to 99 percent by weight of at least one pigment; (B) 1 to 95 percent by weight of at least one water-soluble dispersing additive based on copolymers that consist of the following structural units: (i) 1.0 to 50 mol percent of structural unit B1; a combined total of 50 to 99.0 mole percent of structural units (B2) and (B3); (iii) 0 to 49 mole percent of structural unit (B4).

Easily dispersible solid pigment preparations

The invention relates to an aqueous pigment preparation comprising (A) at least one organic and/or inorganic pigment, (B) dispersants and/or surfactants, (C) a trihydric or higher polyhydric alkoxylated alcohol, (D) a polyglycol alkyl ether, (E) if desired, hydrotropic oligomers and/or polymers, (F) if desired, fats, oils or fatty acids, (G) if desired, further additives typical in the preparation of aqueous pigment dispersions, and (H) water.

Water-based pigment preparation

An aqueous pigment preparation containing: (A) at least one organic and/or inorganic pigment; (B) at least one water-soluble or water-dispersible non-ionic oligoester or polyester, which is obtained by the polycondensation of dicarboxylic acid and glycol components, said oligoester or polyester comprising I) one or more aromatic dicarboxylic acids, their esters or anhydrides, II) C-Calkenediols, III) poly (C-C-alkene)glycols and/or methylpoly(C-Calkene)glycols, IV) optional water-soluble addition products of alkene oxide on C-Calcohols, C-Calkylphenols or on C-Calkylamines and V) one or more optional polyols; (C) optional additional dispersants and surfactants that are conventionally used to produce aqueous pigment dispersions; (D) optional additional additives that are conventionally used to produce aqueous pigment dispersions; and (E) water.
