Polyester EA toner comprising furan

摘要

Methods of making a bio-based polyester resin by polycondensing a polyol with a polyacidic furan are described. The polyol can be a rosin diol obtained by reacting a rosin acid and a glycerol carbonate. The polyacidic furan is obtained from a bio-based product. The resin may be used in manufacturing toner for imaging devices.

1. A method of making a bio-based polyester resin for making toner comprising polycondensing a polyol with a polyacidic furan, optionally in the presence of a catalyst to form the bio-based polyester resin for making toner, wherein said polyol comprises a rosin diol, wherein said rosin diol is obtained by reacting a rosin acid and glycerol carbonate, in the presence of a catalyst comprising 2-methyl-1H-imidazole, wherein the polyacidic furan is obtained from a bio-based product.
