ABSTRACT:
A composition for rendering materials fluorescent substantially without visible trace comprises an organic fluorescent compound dissolved in a solvent characterized by a boiling point or distillation range at atmospheric pressure of between about 12.degree.-35.degree. C. The preferred composition comprises fluorescent azoles, such as 2-(o-Hydroxyphenyl)benzoxazole, 2-(o-Hydroxyphenyl)benoxazole, and derivatives thereof dissolved in volatile halocarbon solvents, such as Fluorotrichlormethane, 1,1-Dichloro-1-Fluoroethane, and 2,2-Dichloro-1,1,1-Trifluoroethane. The resultant product is particularly suited for marking currency, papers, fabrics, and other porous webs and surfaces. Treated surfaces appear normal in white light, are highly fluorescent under UV light and feature excellent transfer of the fluorescent compound to fingertips and other surfaces in direct or glancing contact.
