摘要

Process for the preparation of pigment preparations easily distributable in hydrophilic and hydrophobic media, characterized in that an organic pigment in fine distribution is contacted with a colorless, slightly colored aromatic compound of the formula i ** formula ** in which a is an aromatic ring system with at least 9 ring atoms and more than one ring, b is a direct bond or bivalent linking groups, r are aliphatic carbon chains with more than 5 carbon atoms, which can carry hydroxy groups and/or carboxy, x and y are, independently of each other, any substituents, n and m are, independently of each other, 0, 1 or 2, and p is 1 to 4, until the pigment particles are enveloped by the compound of the formula i and present hydrophilic and hydrophobic properties.
