Abstract: This application relates to a part that includes a metal oxide layer having pore structures. In some embodiments, dye molecules having aromatic rings can be disposed within at least one of the pore structures. Additionally, the at least one pore structures can include dispersion molecules, where the dispersion molecules form non-covalent interactions with the dye molecules. By forming non-covalent interactions between the dye molecules and the dispersion molecules, the aromatic rings of the dye molecules are prevented from forming other non-covalent interactions with other dye molecules. Additionally, techniques for chemically stabilizing the color dye bath for dyeing anodized parts are also described.

Abstract: This application relates to a method for forming an enclosure for a portable electronic device, the enclosure including a metal substrate that is overlaid by an anodized layer. The method includes dyeing the anodized layer by exposing pores of the anodized layer to a dye. The method further includes sealing the dye within the pores by exposing the anodized layer to a zinc-based sealing solution, where an external surface of the anodized layer having the pores that are sealed includes an amount of zinc between about 3 wt % to about 6 wt %.
