Title: ARTICLE WITH AESTHETIC SUBSTRATE
Abstract:
Provided are an article with aesthetic substrate and a method of securing a layer of colloidal crystals (2) to a substrate (4). The article comprises a layer of colloidal crystals (2) on the substrate (4) and a layer of waterborne coating (6) applied to the colloidal crystals (2), to enhance durability of an aesthetic effect provided by the colloidal crystals (2). The method involves depositing a layer of colloidal crystals (2) formed of mono-dispersed particles on the substrate (4), subsequently, a layer of water-borne coating (6) is applied to the layer of colloidal crystals (2). To be effective, the water-borne coating (6) should have a curing temperature that is less than the polymer glass transition temperature of the mono-dispersed particles forming the colloidal crystals (2). The water-borne coating (6) penetrates through the colloidal crystals (2) to the substrate (4) thus retaining the colloidal crystals (2) in place. The curing temperature of the water-borne coating (6) ensures that the colloidal crystals (2) are not damaged by the process for curing the coating.
