Publication number: 20160145437Abstract: The present application is directed to combination effect pigments comprising an effect pigment and carbon black, wherein the carbon black is adherently deposited on the effect pigment interposed within the substrate and at least one subsequent layer of the effect pigment. This structure of the combination effect pigment results in advantageous non-staining properties of the pigment and maximizes color effects of the carbon black.Type: ApplicationFiled: December 22, 2014Publication date: May 26, 2016Inventors: Lizzabeth Ponce, Geoffrey Johnson, Louis R. Cerce, Steven Jones, Curtis J. Zimmermann

Patent number: 8916234Abstract: This invention is directed to a method of modifying the refractive index of multilayer thin films structure comprising high refractive and low refractive index layers, where the high refractive and low refractive index layers are of the same material, the method comprises a) depositing a first layer of film of a refractive index on a substrate; b) depositing a second layer of film having a different refractive index onto the first layer of film; and c) depositing a third layer of film having a different refractive index from the second layer of film onto the second layer of film, and compositions thereof. In certain embodiments, this multilayer thin film structure of this invention is directed to decorative applications.Type: GrantFiled: May 14, 2009Date of Patent: December 23, 2014Assignee: BASF CorporationInventors: Thomas Chirayil, Curtis J. Zimmermann, Geoffrey M. Johnson

Patent number: 8282729Abstract: 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.Type: GrantFiled: July 26, 2011Date of Patent: October 9, 2012Assignee: BASF CorporationInventors: Daniel S.
