SILVERY PRODUCT WITH APPLIED LOW-EMISSION COATING, WHICH HAS ABSORBING LAYER AND LOW TRANSMISSION OF VISIBLE LIGHT Russian patent published in 2020 - IPC B32B17/06 

FIELD: manufacturing technology.

SUBSTANCE: low-emissivity coating on substrate (for example, glass substrate) includes at least first and second infrared (IR) radiation reflecting layers (for example, silver-based layers) which are separated from each other by contact layers (for example, NiCr-based layers), layer containing silicon nitride, and an absorbent layer consisting of such material or including such material as niobium-zirconium, which can be oxidised and/or nitrided. Absorbing layer is configured to provide article with coating with silver color when reflected from side of glass (equivalent to reflection from outer side in window unit-insulating glass, if coating is made on surface No. 2 of window unit-double-glazed unit). In some embodiments, the coated article (in monolithic form and/or in the form of a window unit/double-glazed unit) has low transmission of visible light (for example, 15–45 %, more preferably 22–39 %, and most preferably 24–35 %). In some embodiments, the coated article can be subjected to heat treatment (for example, thermal quenching and/or thermal bending).

EFFECT: disclosed is a silvery product with a low-emission coating which has an absorbing layer and low transmission of visible light.
