Pigment Type

inorganic

Chemical Name

Properties

Cadmium Red PR108:1 shares the properties of Cadmium Red PR108, except that it is slightly more orange in tone and has lower tinting strength.

Permanence

Cadmium selenosulfide lithopone has excellent lightfastness. It shares the permanence of pure cadmium selenosulphide (Cadmium Red PR108).

Toxicity

Cadmium Red is a known human carcinogen. It is extremely toxic if inhaled and slightly toxic if ingested. Barium sulfate is extremely insoluble in water, and thus is not biologically active. It is used medically as a contrast medium in radiological procedures.

History

Cadmium Red PR108:1 is cadmium red pigment that contains 15% or more barium sulfate. It is used to create a fuller spectrum of reds and oranges from cadmiums, and also to create a less expensive alternative to PR108.

Alternate Names

Cadmium Red Scarlet, Cadmium Red Light
