Title: The Innovative Journey of Steven J. Sargeant

Introduction

Steven J. Sargeant, an accomplished inventor based in Honeoye Falls, NY, has made significant contributions in the realm of photographic materials. With a robust portfolio of six patents, Sargeant's innovations focus primarily on enhancing the properties and effectiveness of dye-forming couplers within polymers.

Latest Patents

Among Steven's latest inventions is the "Polymer Co-precipitated Coupler Dispersion." This innovative process involves coprecipitating a photographic material such as a dye-forming coupler inside a base ionizable polymeric particle. The procedure starts by combining a surfactant solution with a second flow that includes a water-miscible solvent, base, water, and the photographic material. This mixture is then neutralized, resulting in a colloidal dispersion that exhibits remarkable photographic activity and dye stability.

Another noteworthy patent is the technique for "Increased Photographic Activity Precipitated Coupler Dispersions." In this method, a single-step coprecipitation process incorporates a base deprotonation compound, usually a liquid carboxylic acid, into the precipitated particles. This approach enhances the reactivity of dispersions, even for previously unreactive hydrophobic couplers. The combination of aqueous surfactant solutions and basic solutions further solidifies the effectiveness of the resulting photographic materials.
