Title: Innovations in Toner Technology by Kasturi Rangan Srinivasan

Introduction

Kasturi Rangan Srinivasan, based in Longmont, Colorado, has made significant contributions to the field of toner technology, holding an impressive portfolio of 40 patents. His work primarily focuses on chemically prepared toner compositions, which have important applications in electrophotographic printing systems.

Latest Patents

Among his latest innovations are two noteworthy patents. The first, titled "Chemically Prepared Core Shell Magenta Toner Using a Borax Coupling Agent and Method to Make the Same," details a novel method for producing a magenta toner composition. This process involves the agglomeration of a first polymer emulsion with a magenta colorant dispersion and a release agent dispersion to create toner cores. The introduction of a borax coupling agent enhances the properties of these toner cores. A second polymer emulsion is then combined to form the toner shells, resulting in efficient magenta toner particles that minimize pigment aggregation.

The second patent, "Crash Cooling Method to Prepare Toner," discloses a method that utilizes a crash cooling process. In this process, a toner slurry at elevated temperatures is rapidly cooled by adding it to cold water. This technique significantly improves toner usage efficiency in the production of various toner types, including polyester and styrene acrylic toners with enhanced properties thanks to the borax coupling agent.
