ABSTRACT:
An easy method for preparing pigment preparations on wax basis in an aqueous medium is treating the pigment in the aqueous medium with a solution of the wax in an organic solvent. The so-obtained preparations are easily dispersible in lacquers and plastic masses and allow to obtain the full tinctorial strength of the pigment without needing much energy for dispersing the pigment in the substrate.
