FIELD: physics, optics.
SUBSTANCE: invention relates to the system of sunlight reflecting coatings. The system of coatings comprises two layers of coatings. The layer of the first coating a) has CIELAB L* value no more than 40 and includes: i) film-forming resin and ii) the pigment absorbing visible radiation and transparent for infrared radiation. The layer of the second coating b) is applied below, at least, a part of a layer of the first coating and includes: i) film-forming resin; ii) the pigment of thin scales of metal or alloy of metal reflecting the infrared radiation, and iii) the pigment absorbing visible radiation and transparent for infrared radiation. The layer of the first coating and the layer of the second coating has contrast ration (L*second/L*first) from 0.8:1 up to 1.6:1. The system of coatings has % of the full solar reflection (FSR) of, at least, 25%, and the layer of the second coating has % FSR of, at least, 25%.
EFFECT: invention allows to create the system of sunlight reflecting coatings.
