PRECIOUS METAL COLOR EFFECT MATERIALS AND PRODUCTION THEREOF

摘要

A precious metal color effect material is composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with a first layer selected from the group consisting of silver, gold, platinum, palladium, rhodium, ruthenium, osmium, iridium and the alloys thereof, which acts as a reflector to light directed thereon, a second layer encapsulating the first layer in which the second layer provides an optically variable reflection of light impinging thereon and a third layer encapsulating the second layer and being selectively transparent to light directed thereon.
