<p>Pigments are disclosed comprising zinc sulfide as a host containing in solid solution at least a sufficient amount of copper indium sulfide as a dopant to alter the color of the zinc sulfide, characterized in that selenium is substituted for at least some of the sulfur. Optionally, barium sulfate may be used as an extender. The pigment may be prepared by jointly precipitating the sulfides of the indicated metals and then firing to an equilibrium temperature to achieve a desired solid solution.</p> |
