Abstract

L'invention concerne l'utilisation d'une composition fluorescente pour la sécurisation d'un produit, ladite composition comprenant une matrice polymère incorporant un composé de la famille des β-dicétonate de difluoroborane de formule I (I) dans laquelle, L1 est une chaine aliphatique insaturée ou inexistant, L2 est une chaine aliphatique insaturée ou inexistant, R1 est un groupement aryle non substitué ou substitué ou un groupement hétéroaryle non substitué ou substitué, R2 est un groupement aryle non substitué ou substitué ou un groupement hétéroaryle non substitué ou substitué, et R3 est choisi parmi hydrogène, un groupement aryle substitué ou non, et un groupement hétéroaryle substitué ou non.The invention relates to the use of a fluorescent composition for securing a product, said composition comprising a polymer matrix incorporating a compound of the difluoroborane β-diketonate family of formula I (I) in which, L1 is a unsaturated or nonexistent aliphatic chain, L2 is an unsaturated or nonexistent aliphatic chain, R1 is an unsubstituted or substituted aryl group or an unsubstituted or substituted heteroaryl group, R2 is an unsubstituted or substituted aryl group or an unsubstituted or substituted heteroaryl group , and R3 is chosen from hydrogen, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group.
