Blacklight paint

Blacklight ink or blacklight-reactive ink is ink that glows under a black light, a source of light whose wavelengths are primarily in the ultraviolet. The paint may or may not be colorful under ordinary light. It is also known as luminous paint or fluorescent paint.

Blacklight paint can be mixed with similar shades of normal pigments, ‘brightening’ them when viewed in sunlight.

‘Day-Glo’ is a registered trademark of the Day-Glo Color Corporation.

The invention of fluorescent paints is attributed to Robert Switzer, who was confined to a dark room after a fall, and his brother Joseph, who was a chemistry major at UC Berkeley, in 1934. They took a black light into the storeroom of their father's drugstore looking for naturally fluorescent organic compounds and from that developed paints.

Blacklight paints and inks are commonly used in the production of blacklight posters. Under daylight, the ultraviolet light ordinarily present makes the colors especially vivid. Under blacklight (with little or no visible light present), the effect produced can be psychedelic. The inks are normally highly sensitive to direct sunlight and other powerful light sources. The fluorescent dyes cause a chemical reaction when exposed to high intensity light sources (HILS) and the visual result is a fading in the colors of the inks. With paper, significant visible change in the color saturation can typically be observed within 45 minutes to one hour of exposure to the HILS. To date, there is no absolute method to prevent this phenomenon, although certain laminations, lacquer coatings and glass or plastic protective sheets can effectively slow the fading characteristics of the dyes.
