IR-REFLECTING AND TRANSPARENT SYSTEM OF LAYERS HAVING COLOUR STABILITY, AND METHOD OF MAKING SAME MANUFACTURE, GLASS BLOCK Russian patent published in 2016 - IPC C03C17/36 

FIELD: optics.

SUBSTANCE: invention relates to thermally treated system layers for glazing for protection against sun. Provided is information on a transparent infrared reflective layer system on a transparent, dielectric substrate SO, a method of its manufacture, and a glass unit for use in said system of layers. System includes a structure of main layer GA with a dielectric main layer GAG lying above structure of UFA functional layer with a metallic functional layer UFAF and a blocking layer UFAB and a structure of coating layer. Structure of intermediate layer ZA is deposited with such thickness that when viewing angle in range from 0 to ±75° relative to normal to substrate surface a * (Rg) and b * (Rg)-colour CIE L * a * b * system colour measurements of reflection from side of substrate are located in range of ≤ 0.

EFFECT: technical result is ensuring high transmission in visible range, low radiating capacity and wide reflection colour point stability.
