VERFAHREN ZUR HERSTELLUNG VON POLYMERUMHÜLLTEN PIGMENTTEILCHEN DURCH PRÄZIPITATION

Described is a process for preparing polymer-enrobed pigment particles, which comprises mixing in the presence of finely dispersed pigment particles a solution of a polymer in a first solvent with a second solvent in which the polymer is substantially insoluble. The pigment particle can be specifica...

Beschreibung
Zusammenfassung:	Described is a process for preparing polymer-enrobed pigment particles, which comprises mixing in the presence of finely dispersed pigment particles a solution of a polymer in a first solvent with a second solvent in which the polymer is substantially insoluble. The pigment particle can be specifically modified by judicious selection of the polymer.
