Provided are: a support frame for pellicle that has both low dust generation property and high light resistance, and further has an ion elution amount which is reduced to the utmost limit to an extent that haze is not generated even when a short wavelength laser is used for exposure light source, a pellicle using the support frame for pellicle, and a method for efficiently manufacturing the support frame for pellicle, support frame for pellicle which comprises a frame member comprising aluminum or aluminum alloy and an inorganic coating layer formed on the surface of the frame member, wherein the main chain of the inorganic coating layer is constituted by a —Si—O—Si—O— bond. An anodized film is preferably formed between the frame member and the inorganic coating layer.

Colored oxide coatings having multiple oxide layers are described. Processes for forming the multilayer oxide coating can include converting a portion of a metal substrate to a primary oxide layer, coloring the primary oxide layer, and depositing a secondary oxide layer on the primary oxide layer. The primary oxide layer and the secondary oxide layer can be at least partially transparent such that a texture of an underlying metal substrate surface is visible through the multilayer oxide coating. A top surface of the secondary oxide layer can be polished to a high gloss to give the multilayer oxide coating an appearance of depth.

Various embodiments of the disclosure relate to an electronic device and relate to an electronic device including a housing formed through anodizing and a method for manufacturing the housing of the electronic device. According to an embodiment of the disclosure, there may be provided an electronic device including a housing at least partially including an electrically conductive material, where a surface of the electrically conductive material is formed of an oxide film layer having a plurality of cavities, where the plurality of cavities are colored in a first color and a second color, and where the first color and the second color are mixed when the second color is deposited on the first color.

A method of manufacturing an interference coating on the surface of an aluminum alloy or aluminum alloys product comprising anodizing and electrochemical dyeing with use of alternating current consisting in that, the electrolyte used during electrochemical dyeing comprises copper (II) sulfate (IV) in an amount from 1 to 100 g/L, boric acid in the amount of 1 to 40 g/L and tartaric acid in the amount of 0.1 to 20 g/L.

The embodiments described herein relate to anodizing and anodized films. The methods described can be used to form opaque and white anodized films on a substrate. In some embodiments, the methods involve forming anodized films having branched pore structures. The branched pore structure provides a light scattering medium for incident visible light, imparting an opaque and white appearance to the anodized film. In some embodiments, the methods involve infusing metal complex ions within pores of an anodized. Once within the pores, the metal complex ions undergo a chemical change forming metal oxide particles. The metal oxide particles provide a light scattering medium for incident visible light, imparting an opaque and white appearance to the anodized film. In some embodiments, aspects of the methods for creating irregular or branched pores and methods for infusing metal complex ions within pores are combined.
