    Abstract: Stable dispersions of solids, especially pigments, are obtained by distributing a solid having acidic groups on its surface in a liquid medium comprising an amine having at least one aliphatic chain of more than 5 carbon atoms, a non-ionic and/or an anionic surfactant having one or more aliphatic chains with a total of more than 5 carbon atoms and an organic water-miscible solvent. These dispersions are easily distributable in hydrophobic and in hydrophilic systems.

    Abstract: Dispersions of inorganic and organic pigments containing an alkylene oxide adduct on long-chain aliphatic amines and an anionic surfactant having an aliphatic radical of 3 to 40 carbon atoms can easily be distributed in hydrophilic and hydrophobic media and yield colorations of high tinctorial strength and purity of shade.

    Abstract: Dispersions containing (a) a pigment, (b) an oxalkylated novolak, (c) urea and/or a compound containing at least 2 long-chain aliphatic groups and which are connected via a bridge member containing ester and/or amide groups, and (d) water and/or agents retarding drying up, and, optionally, usual adjuvants, are useful for pigmenting natural or synthetic materials, especially aqueous systems containing cellulose ethers.

    Abstract: Stable dispersions of pigments are obtained by finely distributing inorganic and/or organic pigments in water and/or agents preventing or retarding the drying-up of the dispersions containing condensation products of aromatic hydroxy compounds and alkanals as well as surfactants, said condensation products and surfactants containing aliphatic carbon chains of more than 5 carbon atoms. The dispersions are compatible with hydrophilic and hydrophobic media.
