Abstract
A nonstaining fingerprint ink is formulated from one or more alcohol soluble dyes, e.g., Acid Black 5 dye, dissolved in one or more fatty acid esters which have at least one available hydroxyl group, e.g., glycerol monoricinoleate, the dye constituting about 5% of the total ink by weight. An applicator, particularly well suited for the ink, includes a pad made of a melt blown calendared fabric encapsulated in a gas impermeable pouch.
