Abstract
A series of resins were synthesized using a range of bio-based materials to control the molecular architecture, and therefore the properties, of the inventive resins. The resins were formulated into toner formulations such as those useful in printers and copiers.

21. A thermoplastic toner composition comprising:
-
a mixture of, a. an amorphous thermoplastic polymer comprising a carboxyl or hydroxyl functional polyester wherein the carboxyl or hydroxyl functional polyester is derived from a dianhydrohexitol, a first diacid moiety, and a second diacid moiety, optionally a monoacid may also be included; and wherein the polymer is derived from at least one bio-based monomer; and the polymer has a Tg between about 50°
C. and about 80°
C.;b. a coloring agent dispersed in the amorphous thermoplastic polymer; and wherein the toner comprises a powder having a mean particle size of less than about 30 um. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
