PRODUCT WITH LOW-EMISSION COATING CONTAINING ABSORBING LAYERS FOR LOW REFLECTION ON FILM SIDE AND LOW PASSAGE OF VISIBLE SPECTRUM Russian patent published in 2017 - IPC C03C17/36 

FIELD: chemistry.

SUBSTANCE: low-emission coating applied on glass substrate contains the following layers: the first and second infra-red (IR) reflecting layers containing silver. The mentioned IR-reflective layers are separated from each other by at least one dielectric layer. The first IR-reflective layer is closer to the glass substrate than the second IR-reflective layer. The first metallic or substantially metallic absorbing layer containing Ni and/or Cr is positioned so that the first absorbing layer is between the glass substrate and the first IR-reflective layer. The second metallic or substantially metallic absorbing layer containing Ni and/or Cr is positioned so that both the first and second IR-reflective layers are between the glass substrate and the second absorbing layer. Each of the first absorbing layer and the second absorbing layer is between and in contact with the dielectric layers containing silicon nitride.

EFFECT: low emissivity, low light transmittance and low reflection coefficient.
