A UV-protective composition for treating substrates comprising one or more water-soluble, cationic, UV-absorbing polymers, wherein the cationic, UV- absorbing polymers are prepared by polymerizing one or more vinyl, allyl or acrylic monomers with one or more vinyl or acrylic monomers that absorb ultraviolet light radiation having a wavelength of about 200 to about 420 nm and a method of treating substrates.
L'invention concerne une composition protégeant des ultraviolets qui permet de traiter des substrats et contient au moins un polymère d'absorption d'ultraviolets cationique, soluble dans l'eau. Ce polymère est préparé par polymérisation d'au moins un monomère vinylique, allylique ou acrylique avec au moins un monomère vinylique ou acrylique qui absorbe les rayonnements de lumière ultraviolette possédant une longueur d'onde comprise entre environ 200 et 420 nm. Ladite invention a également trait à un procédé de traitement de substrats.
