Solid pigment preparations comprising as essential constituents
(A) from 60% to <90% by weight of at least one pigment,
(B) >10% to 40% by weight of at least one anionic surface-active
additive based on acid phosphoric, phosphonic, sulfuric and/or sulfonic
esters of polyalkylene oxides or of reaction products of alkylene oxides
with aliphatic alcohols, with phenol or naphthol, which may each be alkyl
substituted if desired, with aliphatic or aromatic amines or with
aliphatic carboxylic acids or carboxamides or on salts thereof, the
fraction of the phosphorus-containing additive in a mixture of
phosphorus- and sulfur-containing additives being not less than 50% by
weight, and
(C) from 0% to <30% by weight of at least one nonionic surface-active
additive based on polyethers,
with the proviso that component (B) is a phosphoric and/or phosphonic
ester when the fraction of component (C) is 0% by weight,
are made and used for pigmenting macromolecular organic and inorganic
materials.
