PROCESS FOR THE PREPARATION OF DISPERSIONS OF PIGMENTS APLICABLE IN THE PIGMENTATION OF HYDROPHILIC AND HYDROPHOBIC MEDIA

摘要

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.
