Abstract
It has been found that bismuth can be milled into pigment platelets. A metallic pigment comprises bismuth metal and an organic additive. The pigment is platelet shaped. In addition, the platelet shaped pigment comprising bismuth metal can be produced by physical vapor deposition (PVD) methods. In some embodiments, the metallic pigment comprises multiple layers.
