Abstract
A composition of matter (e.g., a molded article) is described. More particularly, the composition of matter includes: (a) a resinous component selected from at least one member of the group consisting of (co)polyester, (co)polycarbonates, acrylonitrile-butadiene-styrene, polyamide, polyurethane, polyalkyl(meth)acrylate and styrene copolymers; (b) at least one water-insoluble dye; (c) a carrier represented by the following formula, R1[—O—(CH2)n]mOR2 wherein R2is butyl, R1 is H, n is 2 or 3, and m is 2–35; (d) an emulsifier that is poly(oxy-1,2-ethanediyl), alpha-phenyl-omega-hydroxy, styrenated; and (e) a particulate or plate-like material, such as metal flakes.
