摘要： Imidomethyl blocked photographic image dyes and dye releasing compounds are useful in photographic elements and processes. The blocked photographic dyes and dye releasing compounds have the structures:
wherein:
X represents the atoms to complete at least one 5- or 6-membered ring; R represents hydrogen, alkyl or 1 to 4 carbon atoms or aryl of 6 to 12 carbon atoms;
-Q-DYE represents the residue of a diffusible photographic dye; and CAR is a ballasted carrier moiety from which the dye moiety is released as a function of silver halide development.-

摘要： @ Ferric ion chelates are useful in analytical compositions, elements and methods for the determination of reductants, or other analytes which can react to produce a reductant. The ferric ion chelate is reduced to ferrous ion and ferric ion coordinating ligand. The ferrous ions then coordinate with a suitable ferrous ion coordinating ligand to form a colored complex. In particular, these compositions and elements are useful for detecting nicotinamide adenine dinucleotide, reduced form or nicotinamide adenine dinucleotide phosphate, reduced form, or an analyte (e.g. an enzyme) which produces the reduced forms of nucleotide in biological fluids.
