ABSTRACT:
Fluorescamine or like compounds react with the epidermis when applied to the skin and form, within about 15 to 30 minutes after application to the skin, a long-lasting reaction product, which is invisible in ordinary light but which fluoresces intensely under ultraviolet light. Such markings resist removal by abrasion and repeated washings. Organic solutions of such compounds, preferably containing a fugitive dyestuff or pigment and used as the marking fluid of a conventional felt-tipped pen, can be used to mark skin for radiological or diagnostic purposes. Inanimate objects can be coated with these compounds to detect human contact therewith.
