摘要

A unique opalescent color effect is produced on a substrate material utilizing a multicoat coating system. The base coat is a nonmetallic primary color coat having an N-4 to N-8 value on Munsell color chart. Directly on top of the base coat there is applied a transparent interference coat containing a polymeric binder and metal oxide encapsulated mica particles in a pigment to binder ratio of 0.06 to 0.13. On top of the previously applied coats is applied a transparent protective clear coat. The resultant coating in addition to being durable to the elements produces a unique opalescent color effect on the substrate material.
