| 摘要 |
The invention relates to a glass substrate (10) provided on a main face with a thin-film multilayer stack comprising a metallic functional layer (40) having reflection properties in the infrared and/or in solar radiation, especially one based on silver or a silver-containing metal alloy, and two antireflection coatings (20, 60), said coatings each comprising at least one dielectric layer (24, 64) based on silicon nitride, said functional layer (40) lying between the two antireflection coatings (20, 60), the functional layer (40) being deposited directly on an underblocker coating (30) lying between the functional layer (40) and the subjacent antireflection coating (20), and an overblocker coating (50), deposited directly on the functional layer (40), lying between the functional layer (40) and the superjacent antireflection coating (60), characterized in that in order for said substrate to be bendable and/or toughenable after the thin-film multilayer stack has been deposited, the underblocker coating (30) comprises a thin nickel-based film deposited in metallic form and having a thickness e such that 0.8 £ e £ 1.8 nm. |
