GOLDEN are continuously testing products to offer the best materials available. To provide bright and lightfast yellows artists need, GOLDEN is introducing Benzimidazolone Yellow Medium and Benzimidazolone Yellow Light, both having ASTM Lightfastness I ratings.
Recent rests reveal that pigments PY3 and PY73, used in Hansa Yellow Light and Hansa Yellow Medium formulations no longer meet ASTM Lightfastness standards for acrylics. As a result, the lightfastness rating on Hansa Yellow labels will change to Fair, but will still be available to artists in open stock displays. Hansa Yellow will be replaced with Benzimidazolone in seven colour blends while maintaining the original colours, including Cadmium Yellow Medium Hue, Green Gold, Indian Yellow Hue, Light Green (Blue Shade), Light Green (Yellow Shade), Permanent Green Light, and Primary Yellow.
