Title: Innovations of Stephen Swingley in Photothermographic Systems

Introduction

Stephen Swingley is an accomplished inventor based in Rochester, NY (US). He has made significant contributions to the field of photothermographic systems, holding two patents that showcase his innovative approach to organic silver salts.

Latest Patents

Swingley's latest patents include "Core/shell silver donors for photothermographic systems comprising an oxidatively more reactive shell" and "Core/shell silver donors for photothermographic systems comprising an oxidatively less reactive shell." The first patent describes a photothermographic element that incorporates silver halide, a blocked developer, a coupler, and core/shell particles. These particles consist of a mixture of at least two non-photosensitive organic silver salts, with a center portion made of a non-photosensitive first organic silver salt and a shell portion made of a non-photosensitive second organic silver salt. The organic silver salt in the shell has a lower pKsp compared to that in the core. The second patent similarly outlines a photothermographic element but features a shell with a higher pKsp relative to the core.
