ABSTRACT:
Color-forming precursor compositions comprising a metal-complexing compound having a plurality of ligand groups and color-activating compositions comprising transition metal salts of oleophilic, organic acids are combined to form dark, permanent images on substrates. The methods and compositions are particularly useful for providing permanent fingerprints and other dermographs.
