Abstract
A color effect material is composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with a first layer which acts as a reflector to light directed thereon, a visibly transparent second organic 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.
Claims16

- (a) a first layer highly reflective to light directed thereon selected from the group consisting of an alloy of copper and zinc, an alloy of aluminum and copper, an alloy of aluminum and zinc, copper and zinc;
- (b) a visibly transparent second organic layer encapsulating the first layer and providing a variable pathlength for light dependent on the angle of incidence of light impinging thereon;
- and
- (c) a selectively transparent third layer to light directed thereon.
