Title: Innovations of James R. Paxson
Introduction
James R. Paxson is a notable inventor based in Walworth, NY (US). He has made significant contributions to the field of toner technology, holding a total of 3 patents. His work primarily focuses on the development of unsaturated polyesters and their applications in toner formulations.
Latest Patents
Paxson's latest patents include innovative solutions for toner technology. One of his patents describes "Unsaturated polyesters with vinyl side chains," which details a low fix temperature toner that exhibits improved blocking performance. This toner comprises a colorant and a toner resin, which is the reaction product of a diacid, diester, or anhydride, a diol, and a vinyl monomer compound. The unique aspect of this invention is the presence of separate polyester and vinyl polymer domains with distinct glass transition temperatures (T.sub.g's). Another significant patent is focused on "Polyester processes for the preparation of toner." This process involves creating a crosslinked polyester through the reaction of a diol or a mixture of diols with a diacid or a mixture of diacids, along with a polyhydric alcohol monomer. The resulting polyhydroxy functional polyester resin precursor is then reacted with a dianhydride or diepoxy functional crosslinking component.
