As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The surface of the article can include the optical element with sections that have different relative thicknesses from one another. A first section imparts a first structural color and a second section imparts a second structural color. The first structural color and the second structural color differ from each other when viewed from the same angle of observation from a viewer having 20/20 visual acuity and normal color vision from a distance of about 1 meter from the article including the optical element.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article includes the optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., cross-sectional structure) of the optical element in certain regions.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article includes the optical element on its surface and the optical element includes one or more layers (e.g., a reflective layer(s), a constituent layer(s), and the like). The optical element can include a plurality of different sections, where each of the different sections have a different relative thickness.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article includes the optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., transverse cross-sectional structure) of the optical element in certain regions.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article can include an optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., transverse cross-sectional structure) of the optical element in certain regions.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article can include the optical element (e.g., a single layer reflector, a single layer filter, a multilayer reflector or a multilayer filter) including one or more layers (e.g., a reflective layer(s), a constituent layer(s), and the like). The surface of the article can include areas of the surface that are at different relative heights from one another and can impart different structural colors.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The present disclosure provides for articles (e.g., structurally colored articles) that exhibit different structural colors in different regions of the article using an optical element, where the optical element has different structures (e.g., cross-sectional structures) in at least two of those regions.

One or more aspects of the present disclosure provide articles of manufacture and components of articles that incorporate an optical element that imparts structural color to the component or the article. The component comprises a cured or curable material, and can include or be made to have a textured surface.

One or more aspects of the present disclosure are directed to components having an optical element that imparts structural color to the component or article. The present disclosure is also directed to articles of manufacture including the component having an optical element, and methods for making components and articles having an optical element that imparts structural color.

The present invention relates to a process for the preparation of thin silver nanoparticle layers, which are produced directly on a substrate as part of a coating or printing process. The layers show different colours in transmittance and reflectance. The layers do not show the typical conductivity of metallic layers, since the particles are essentially discrete particles which are not sintered. The invention further relates to decorative and security elements. When the layers are applied over a security element, such as a hologram, the obtained products show also different colours in reflection and transmission, an extremely bright optically variable image (OVD image) and high purity and contrast. Depending on the thickness of the layer a more or less intensive metallic aspect appears.
