Gamblin 1980 Oils - PO62 Benzimidazolone Orange

Gamblin’s approach is different. 1980 colours contain pure pigments, the finest refined linseed oil, and marble dust (calcium carbonate). Since oil painting began, these three ingredients have made more affordable colours.

Painters experience true colours without homogenized texture or muddy colour mixtures. Gamblin's approach to using traditional raw materials and processes ensures that artists experience the luscious working properties they expect from their oil colours.

Permanent Orange is a modern high-key colour with a pure hue and the same masstone (but more transparent) than Cadmium Orange, and it remains brighter in its tint when mixed with white. Painters cannot mix a secondary with the same purity of this pure hue Orange.

When used thinly, it creates a rich, glowing glaze. It has an average drying time and loses some intensity as it dries.

The benzimidazole pigment group was developed and patented in 1960 by Hoechst A.G., a German chemical manufacturer that was a forerunner of the pharmaceutical company Aventis. The use of benzimidazolone pigments in the auto industry, especially Benzimidazolone Orange, became common in the 1980s because they were common replacements for lead chromate pigments, which were phased out during this period.
