TRANSPARENT WINDOW GLASS Russian patent published in 2020 - IPC C03C17/36 

FIELD: machine building.

SUBSTANCE: present invention relates to transparent window glass and can be used for glazing vehicles. Disclosed is a transparent window glass comprising at least one transparent substrate (1) and at least one electroconductive coating (2). At that, electroconductive coating (2) includes at least four functional layers (3) located one above the other. Each functional layer (3) includes at least material layer (4) with high refraction index ≥1.3, first matching layer (5) above layer (4) of said material with high refraction index, electroconductive layer (6) above the first matching layer (5), the second matching layer (7) over electroconductive layer (6). Thickness of one of electroconductive layers (6) in each case ranges from 5 nm to 25 nm, and total thickness of all electroconductive layers (6) ranges from 20 nm to 100 nm. At least one layer (4) of said material with a high refraction index, located between two electroconductive layers (6), includes a layer of dielectric material (8) with a refractive index of less than or equal to 2.1, and a layer of material (9) with a high refraction index greater than or equal to 2.1. Besides, the coating contains additional layer (4.1) of material with high refraction index ≥1.9, located above upper functional layer (3).

EFFECT: technical result is improved quality of reflecting properties of glass.
