Introduction

Harland J Osborn is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of photographic technology, holding a total of 4 patents. His work has had a lasting impact on the development of photographic elements and coupler compositions.

Latest Patents

Osborn's latest patents include innovations such as phenylsulfamoyl couplers and coupler compositions. These patents disclose ballasted primary and secondary 3'-sulfamoyl-1-hydroxy-2-naphthanilide couplers, along with compositions and photographic elements that incorporate these couplers in coupler solvent particles. The coupler solvent particles consist of a combination of a coupler solvent and the coupler, which allows for the formation of microcrystalline dyes. Remarkably, these microcrystalline dyes exhibit a broadened absorption characteristic in the 750 to 850 nm region of the spectrum. Dye images with such absorption characteristics are particularly suited for creating integral infrared absorbing sound tracks in photographic elements, including motion picture projection films.
