Abstract:
A method of manufacturing a substrate coated with a transparent, colored coating, the method comprising:(1) coating the substrate with a coating composition comprising:(A) at least one element which is able to form a vitreous, crystalline, or partially crystalline oxide, in the form of a compound which on heat treatment yields the oxide and is present as a sol or solution in an at least predominantly aqueous medium, as the matrix-forming component; and(B) at least one member selected from the group consisting of metal colloids, metal compound colloids, metal alloy colloids, and metal compounds which form metal colloids under reducing conditions, as the coloring component, and(2) heat-curing the resulting coating at a temperature sufficient to cause formation of the oxide of the at least one element which is able to form a vitreous, crystalline, or partially crystalline oxide, thereby manufacturing the coated substrate.
