Embodiment Construction

[0054] Provides an omnidirectional structural color. The omnidirectional structural color is in the form of a multilayer film (also referred to herein as a multilayer stack) that reflects a narrow band of frequencies within the visible spectrum when viewed from an angle between 0 and 45 degrees. electromagnetic radiation with little or no noticeable color shift. Multilayer films can be used as pigments in coating compositions, structurally continuous films, and the like.

[0055] The multilayer film includes a multilayer stack having a first layer and a second layer extending across the first layer. In some cases, the multilayer stack reflects narrowband electromagnetic radiation having a FWHM of less than 300 nm, preferably less than 200 nm, and in some cases less than 150 nm. When the multilayer stack is exposed to broadband electromagnetic radiation (such as white light) and the multilayer stack is viewed from an angle between 0 and 45 degrees, the multilayer film also ha...

Abstract

The invention relates to a non-color shifting multilayer structure and protective coating on the same, and specifically, provides a color pigment of an omni-directional structure comprising a protective coating. The segment comprises a first layer of a first material and a second layer of a second material, and the second layer extends accross the first layer. In addition, when the segment is exposed to wide-band electromagnetic radiation and is observed at the angle of 0-45 degrees, the segment reflection has reserved full width at half maximum (FWHM) of below 300nm and an electromagnetic radiation band of reserved color shifting of below 30 degrees. The segment comprises a weathering coating which covers the external surface of the segment and makes the relative photocatalytic activity of the segment reducing at least 50%.
