Latest Patents

One of Ciurca's latest patents involves thiazolyl couplers and coupler compositions. These compositions are designed for use in photographic elements, particularly those that utilize ballasted 1-hydroxy-2-naphthamide couplers. The couplers are N-substituted with a thiazolyl group, which is further substituted with a phenyl group. This innovative approach allows for the creation of coupler solvent particles that combine a coupler solvent with the coupler itself. This combination facilitates the formation of microcrystalline dyes, which exhibit broadened absorption characteristics in the 750 to 850 nm region of the spectrum. Such dyes are particularly effective for forming integral infrared absorbing sound tracks in photographic elements, including motion picture projection films.
