Abstract
The invention relates to a glass substrate with interference coloration for a facing panel, comprising a glass sheet covered on one of the faces thereof by a stack of coatings including successively at least: a first transparent coating made from a dielectric material having an optical thickness at least greater than or equal to 5 nm and at most less than or equal to 258 nm; a semi-transparent functional coating having a geometric thickness at least greater than or equal to 0.1 nm and at most less than or equal to 50 nm; a second transparent coating made from a dielectric material and having an optical thickness at least greater than or equal to 20 nm and at most less than or equal to 300 nm; and a coating providing opacity or quasi-opacity and having a geometric thickness at least greater than or equal to 30 nm.
