Title: James J Huson: Innovator in Photographic Couplers

Introduction

James J Huson is a notable inventor based in Penfield, NY (US). He has made significant contributions to the field of photographic chemistry, particularly in the synthesis of phenolic cyan-dye-forming couplers. His work has implications for the development of photographic materials and processes.

Latest Patents

Huson holds a patent for a method of synthesizing phenolic cyan-dye-forming photographic couplers. This innovative process involves synthesizing couplers characterized by a p-cyanophenylureido group in the 2-position of the phenol. The method achieves high yields by contacting a coupler intermediate with a hydrogen donor in the presence of a transition metal catalyst. This results in the formation of the corresponding 2-(p-cyanophenylureido)-5-aminophenol, which is then reacted with an acylating agent to create the final phenolic cyan-dye-forming coupler. He has 1 patent to his name.
