Title: Innovations by Ashley Schafer Grant

Introduction

Ashley Schafer Grant is an accomplished inventor based in Lexington, KY (US). He has made significant contributions to the field of toner technology, holding a total of 5 patents. His work focuses on improving the quality and performance of toner compositions used in printing.

Latest Patents

One of his latest patents is titled "Chemically prepared core shell magenta toner using a borax coupling agent and method to make the same." This invention describes a method for producing a chemically prepared magenta toner composition. The process involves combining and agglomerating a first polymer emulsion with a magenta colorant dispersion that contains a single azo magenta pigment and a release agent dispersion to form toner cores. A borax coupling agent is then added to these toner cores. Subsequently, a second polymer emulsion is combined and agglomerated with the toner cores to form toner shells around them. The aggregated toner cores and shells are fused to create magenta toner particles, ensuring that the single azo magenta pigment does not aggregate into clusters on the outer surface of the core.

Another notable patent is "Toner formulation having a silane surface treated on its outer surface and method of preparing the same." This invention includes a core made up of a first polymer binder, a colorant, and a release agent, with a shell formed around the core that includes a second polymer binder. A borax coupling agent is positioned between the core and the shell, along with an alkoxysilane hydrocarbon that is bonded to the outer surface of the shell through a hydrolytic deposition process. This treatment enhances charge stability in hot and humid environments, ultimately improving toner quality by reducing toner dusting, fuming, and the generation of ultra-fine particles.
