1. A glass article having anti-sun properties comprising at least one glass substrate provided with a stack of layers, wherein the stack of layers comprises, successively from a surface of said at least one glass substrate:
a first module M1 consisting of a layer based on a dielectric material with a thickness e1 or of a set of layers based on dielectric materials with a cumulative thickness e1, said thickness e1 being between 1 and 100 nm,
a layer TN1 comprising titanium nitride, with a thickness of between 2 nanometers and 80 nanometers,
a second module M2 consisting of a layer based on a dielectric material with a thickness e2 or of a set of layers based on dielectric materials with a cumulative thickness e2, said thickness e2 being between 5 and 100 nm,
wherein an intermediate layer is deposited between said layer TN1 and said first module M1 and/or between said layer TN1 and said second module M2, said intermediate layer between said layer TN1 and said first module M1 and/or between said layer TN1 and said second module M2 having a thickness of between 0.2 nm and 6 nm,
wherein said intermediate layer is deposited by sputtering and is selected from a layer consisting of aluminum, titanium, silicon and any combination thereof, and
wherein the stack of layers that is in contact with the glass article does not contain any layers based on silver, platinum or gold.
