  • Cobalt complex amplification imaging system with blocked dye precursor
    Patent number: 4124392
    Abstract: An imaging system is provided wherein a blocked dye precursor is activated by an amine to an unblocked form which, in the presence of an inert cobalt (III) complex containing amine releasing ligands, undergoes a redox reaction to form a dye. The amine generated during the redox reaction causes further dye formation, giving increased speed.
