FIELD: chemistry.
SUBSTANCE: invention relates to a dyeing composition, including a marking component and reduced indium-tin oxide (r-ITO), wherein r-ITO in powder form has a median particle size ranging from 10 nm to 10 mcm, weight ratio In: Sn less than 12:1 and exhibits a lightness (L*) according to 1976 CIE (L*, a*, b*) space, of not more than 50, for use in marking purposes. Described also is a substrate, coated with dyeing composition, packaging material for liquid food products, method of marking coated substrate in packaging material for liquid food products and use of reduced indium-tin oxide for laser marking purposes.
EFFECT: technical result is providing dyeing compositions with good marking properties.
