  • Patent number: 4701420
    Abstract: Ferric ion chelates are useful in analytical compositions, elements and methods for the determination of reductants, or other analytes which can produce a reductant. The ferric ion chelate is reduced to ferrous ion, which coordinates with a suitable ferrous ion coordinating ligand to form a colored complex. In particular, these compositions and elments are useful for detecting nicotinamide adenine dinucleotide, reduced form (NADH) or nicotinamide adenine dinucleotide phosphate, reduced form (NADPH), or an analyte (e.g. an enzyme) which produces NADH or NADPH in biological fluids.

  • Patent number: 4555478
    Abstract: A process of obtaining highly stable color images comprises use of an element which has a support having thereon at least one silver halide emulsion layer having associated therewith an essentially colorless, immobile, ligand-releasing compound of the structure LIG-X. In this structure, LIG is a ligand which is capable of complexing with metal ions (e.g. ferrous ions) to form a metal complex dye, and X is a group which, as a function of silver halide development, is cleaved from LIG. A color image is formed by developing the described element after imagewise exposure with a developing agent to imagewise cleave the bond between the LIG and X, and treating the developed element with metal ions (e.g. ferrous ions) to form a metal complex dye image.
