Patent No. U.S. 6,924,035 B2
BASF Aktiengesellschaft has received a patent for a process for preparing polymer-enrobed pigment particles, which is comprised of dissolving a polymer in a first solvent mixing the solution of the polymer in the first solvent with a second solvent which contains finely dispersed pigment particles and in which the polymer is substantially insoluble, the second solvent being miscible with the first solvent, whereby the polymer is precipitated from the mixture of solvents onto the finely dispensed pigment particles wherein the first solvent is selected from organic water-miscible solvents.
