Description

Article having structural color and method of making a structural colored article The application is a divisional application of application number 201811142410.4, application number 2018, 9, 28, application of the title of "article with structural color and method for manufacturing structural colored article". Cross Reference to Related Applications The present application claims the U.S. provisional application serial No. 62/565,299 filed on 29 of 2017, 9, and the U.S. provisional application serial No. 62/633,666 filed on 22 of 2018, 2, and the U.S. provisional application serial No. 62/565,306 filed on 29 of 2017, 9, and the U.S. provisional application serial No. 62/565,313 filed on 29 of 2017, "STRUCTURES HAVING STRUCTURAL COLOR AND METHODS AND SYSTEMS FOR MAKING STRUCTURES HAVING STRUCTURAL COLOR", and the rights and priorities of the U.S. provisional application serial No. 62/565,310 filed on 29 of 2017, 9, "STRUCTURES HAVING STRUCTURAL COLOR AND METHODS AND SYSTEMS FOR MAKING STRUCTURES HAVING STRUCTURAL COLOR", the disclosures of which are incorporated herein by reference in their entireties. Background The structural color is caused by the physical interaction of light with micro-or nano-features of the surface, as compared to the color resulting from the presence of a dye or pigment that absorbs or reflects light of a particular wavelength based on the chemical properties of the dye or pigment. Color from dyes and pigments is problematic in many respects. For example, dyes and pigments and their related chemicals used in the manufacture and incorporation into finished products may not be environmentally friendly. Drawings Further embodiments of the present disclosure will be more readily understood when the following detailed description of the various embodiments of the disclosure is read in conjunction with the accompanying drawings. Fig. 1A-1B illustrate footwear including the structural color structures of the present disclosure. Fig. 2A-2B illustrate side views of exemplary optical layer structures of the present disclosure. Description of the invention The present disclosure provides articles of footwear and methods of manufacturing articles of footwear that exhibit a structural color through the use of an optical layer structure, wherein the structural color is a visible color that is produced at least in part by an optical effect (e.g., by scattering, refracting, reflecting, interfering, and/or diffracting light of visible wavelengths). The structural color imparts an aesthetically attractive color to the article without the use of inks or pigments and without the environmental impact associated with their use. The optical layer structure may be used alone or alternatively with a textured surface (textured surface) (e.g., as part of a texture), a primer layer, or both to create a structural color. The textured surface and/or primer layer may be part of the optical layer structure or may be separate from the optical layer structure, but when used with the optical layer structure, may produce a structural color. In other words, while the optical layer structure alone produces the first structural color, the combination of the optical layer structure with the textured surface and/or the primer layer produces the second structural color. Based on color parameters such as hue, brightness, iridescence type or any combination thereof, the second structure color is different from the first structure color produced by the optical layer structure alone. In this case, the combination of the optical layer structure and the textured surface and/or primer layer produces a structural color of the article of footwear. After the optical layer structure is disposed on the article of footwear, the article exhibits a different color than the lower surface of the article without the need to apply additional pigments or dyes to the article. For example, the structural color may be different from the color of the lower surface of the article based on color parameters such as hue, brightness, iridescence type, or any combination thereof. In a particular example, the structural color and the color of the lower surface of the article are different in hue and iridescence type, wherein the structural color appears iridescent when viewed from at least two different angles separated by 15 degrees, and the color of the lower surface is not iridescent. The optical layer structure may be disposed (e.g., attached, adhered, bonded, joined) to a lateral-facing side or surface of the footwear, such as on the upper and/or sole structure. The optical layer structure may be incorporated into the sole structure by incorporating it into a cushioning element, such as a bladder or foam. The sole structure and/or the upper may be designed such that one or more portions of the structural coloring component are visible in the final article of footwear through a transparent component or the like that includes an opening or covers the
