The invention relates to a substrate ( 10 ), especially a transparent glass substrate, provided with a thin-film multilayer coating comprising an alternation of n functional layers ( 40 ) having reflection properties in the infrared and/or in solar radiation, especially metallic functional layers based on silver or on metal alloy containing silver, and (n+1) dielectric films ( 20, 60 ), where n≧1, said films being composed of a layer or a plurality of layers ( 22, 24, 62, 64 ), at least one of which is made of a dielectric material, so that each functional layer ( 40 ) is placed between at least two dielectric films ( 20, 60 ), characterized in that at least one functional layer ( 40 ) includes a blocker film ( 30, 50 ) consisting of at least one interface layer ( 32, 52 ) immediately in contact with said functional layer, this interface layer being based on titanium oxide TiO x . |
