PROBLEM TO BE SOLVED: To provide a polyester latex and process for making the same, wherein the formulation exhibits improved stability with narrow particle size distribution and less latex sedimentation.SOLUTION: A process includes: mixing at least one polyester resin with at least one solvent to form a resin mixture; adding water to cause phase inversion and form a polyester latex; adding at least one buffering agent to the phase inverted mixture to stabilize the phase inverted mixture; and subsequent to the buffering agent addition, substantially removing the at least one solvent from the phase inverted mixture. |
