FIELD: marking of products.
SUBSTANCE: invention relates to the field of fluorescent dyes and optical brighteners of rubbers and polymer materials, namely, the use of phenylcyanocoumarin derivatives as fluorescent markers for the marking and identification of rubber products. The use of one or more compounds from the group consisting of phenylcyanocoumarin derivatives as fluorescent markers in the marking and identification of rubber products.
EFFECT: technical result is the expansion of the spectrum of fluorescent markers used for hidden marking of rubber products, increasing the stability of fluorescent markers at high operating temperatures of rubber products.
