Abstract
A fingerprint ink is formulated from a solvent carrier and a low structure carbon dispersion. Carbon particles with an agglomerate size of less than 100 millimicrons are dispersed in a hydrocarbon soluble oleo resin to form the low structure carbon dispersion, with the carbon particles accounting for about 40% to 60% of the total dispersion and the dispersion accounting for 20% or less of the total ink formulation.
