OPTICAL PRODUCTS WITH PIGMENT COATINGS REFLECTING INFRARED RADIATION Russian patent published in 2022 - IPC G02B5/20 G02B5/26 B32B17/10 

FIELD: optics; glazing.

SUBSTANCE: invention relates to optical products, such as films reflecting infrared rays for use in car and architectural windows. Optical products in the form of film include polymer substrate equipped with a metal layer reflecting infrared radiation on its outer surface that is subjected to oxidation. These optical products are additionally equipped with protective coating containing one or more of metal oxide or metal nitride deposited right on the metal layer reflecting infrared radiation using chemical deposition from a vapor phase. These optical products are additionally equipped with composite pigment coating deposited on protective coating, including at least the first layer and the second layer, at least one of which contains the first pigment, wherein each of the first layer and the second layer includes a binding group component, wherein these binding group components together form a pair of supplementing binding groups.

EFFECT: invention provides for obtaining optical products that satisfy the requirements of turbidity, transparency, surface homogeneity, ultraviolet radiation resistance and product durability for modern commercial window films, as well as for colored and/or protective films for car windows and vehicles that are resistant to oxidation, and allow for application of the pigmented layer of coating, and that are produced by an environmentally-friendly water-based coloring method at ambient temperature and pressure.
