Abstract
A method of making pigments, such as special effect pigment includes forming a first slurry including a substrate, a polymer precursor, and a radical initiator; forming a solution including an emulsifier; and combining the first slurry and the solution so that the substrate is encapsulated by a first coating. Special effect pigments formed by the method are also disclosed.
