Abstract:
1. A process for producing a coated substrate, the process comprising: (I) depositing, by sputtering, at least one material selected from the group consisting of a metal M, a nitride of the metal M, a carbide of the metal M, and an oxygen-substoichiometric oxide of the metal M on at least part of a surface of a substrate, to obtain an intermediate film having a physical thickness of 30 nm or less on the substrate surface, wherein the intermediate film is not deposited above or beneath a titanium-oxide-based film; and (II) heat treating the intermediate film while directly contacting at least part of a surface of the intermediate film with an oxidizing atmosphere, to obtain oxide film comprising the metal M and having a physical thickness of 30 nm or less on the substrate surface, wherein a temperature of the substrate during the heat treatment does not exceed 150° C., wherein the oxide film is not part of a multilayer comprising a silver film, and wherein the heat treating is carried out with laser radiation and a power per unit area of the laser radiation at the intermediate film is greater than or equal to 20 kW/cm
