Fluorescent Acrylic Colors are intense, brilliant colors, produced from dyes surrounded by a polymer coating. Because fluorescent colors are transparent, greater intensity is achieved by applying them over bright white surfaces. Fluorescent Colors are not lightfast. For permanency, a topcoat of GOLDEN MSA Varnish with UVLS (UltraViolet Light Stabilizers) is recommended, although varnish and top coats will eliminate the fluorescent "glow" under black light. ABOUT GOLDEN Golden Acrylic Colours are made by the Golden family in upstate New York. Sam Golden had been making paint in New York since the 1930s, and released the first commercially available acrylic, Magna, in 1947. Throughout the Fifties and Sixties he continued to develop his colours and mediums in close partnership with leading art practitioners. In the mid-Seventies, he attempted to retire to up-state New York, but too many artists protested that they were reliant on his products, so he started Golden Paints with his son Mark in the early Eighties. The Golden Artist Colors pay special attention to the latest technological advances in pigment and binders, and continue to work closely with artists to develop new materials. They were the first to develop a water-tension-breaker, the first to use Quinacridone pigments, the first to develop Zinc White for acrylic, the first to use Interference colours, and their latest ground-breaking products include OPEN Acrylics and Digital Mix Media.
