HEAT-TREATED COATING PRODUCT WITH IR-REFLECTING LAYERS BASED ON TITANIUM NITRIDE AND NICKEL-CHROMIUM Russian patent published in 2021 - IPC C03C17/34 

FIELD: glazing.

SUBSTANCE: invention relates to products with coating that can be used for glazing. The proposed product contains a coating supported by a glass wafer. The coating contains the first dielectric layer containing silicon nitride; the first infra-red(hereinafter – IR)-reflecting layer containing Ni and Cr on the glass wafer above at least the first dielectric layer; the second dielectric layer containing silicon nitride above the first IR-reflecting layer; the second IR-reflecting layer containing titanium nitride above at least the second dielectric layer; the third dielectric layer containing silicon nitride above at least the second IR-reflecting layer. The coating product has visible light transmittance coefficient of approximately 12-70%, visible light reflection coefficient on the glass side of no more than approximately 16%, visible light reflection coefficient on the membrane side of no more than approximately 16%, a* value when reflected from the glass side from -8 to +1.6 and a* color value when reflected from the membrane side from -8 to +1.6. A method for producing such a product is also revealed.

EFFECT: improvement of the optical characteristics, in particular providing a combination of acceptable visible light transmittance, preferably color when reflected, a low level of SF, a low level of SHGC and a high LSG for a product with coating when used in windows.
