PROCESS FOR PRODUCING POLYESTER LATEX WITH BIO-BASED SOLVENT

摘要

PROBLEM TO BE SOLVED: To provide a process for producing a polyester latex with a bio-based solvent.

SOLUTION: The process for making a latex emulsion suitable for use in a toner composition includes: bringing at least one polyester resin into contact with a bio-based solvent to form a resin mixture; adding a neutralizing agent and deionized water to the resin mixture; removing the solvent from the formed latex; and recovering the emulsion. The solvent removed from the formed latex may be re-used, making the process very environmentally friendly.
