Abstract:
A phase inversion emulsification process includes dissolving a polyester resin in a mixture comprising (1) an organic solvent, (2) a first portion of a total amount of neutralizing agent, and (3) a first portion of water, neutralizing the dissolved polyester resin with a second portion of neutralizing agent, the second portion of neutralizing agent including the remaining amount of the total amount neutralizing agent, forming an emulsion by adding a second portion of water after the neutralizing step, and removing a portion of the organic solvent from the emulsion to provide a latex.
