Abstract: A multilayer effect pigment includes a transparent substrate, a layer of high refractive index material on the substrate, and alternating layers of low refractive index and high refractive index materials on the first layer, the total number of layers being an odd number of at least three, all adjacent layers differing in refractive index by at least about 0.2 and at least one of the layers having an optical thickness which is different from all of the other layers. The resulting multilayer effect pigment is not a quarter-wave stack. The present effect pigments may be used in cosmetic and industrial applications.

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.

Abstract: Non-bleeding, non-agglomerated, lustrous colored combination pigments constitute a platy substrate and absorption colorant bound thereto with metal hydroxides and one or more hydrolyzed silane coupling agents.

Abstract: A silver/gold coated laminar substrate pearlescent product is improved by incorporating rhodium in an amount of up to about 2% into the coating and/or by overcoating with a silane in an amount of up to about 5%.

Abstract: A 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 silicon, aluminum, titanium nitride and mixtures thereof, which acts as a reflector to light directed thereon, a second layer encapsulating the first layer in which the second layer provides a variable pathlength of light dependent on the angle of incidence of light impinging thereon and a third layer being selectively transparent to light directed thereon.

Abstract: A color effect material is composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with copper, zinc, an alloy of copper, or an alloy of zinc first layer 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.
