Abstract[English]
The present invention provides a security tape or security label comprising a substrate and a UV curable hot melt pressure sensitive adhesive (HMPSA), wherein the HMPSA comprises: 1) a UV-curable acrylic polymer that is a reaction product of a reaction composition comprising one or more acrylic monomers and one or more photoinitiators, and 2) optionally one or more additional ingredients, wherein said acrylic polymer is crosslinkable through said photoinitiator groups upon exposure to ultraviolet light.[French]
La présente invention concerne un ruban ou une étiquette de sécurité comprenant un substrat et un adhésif autocollant thermofusible durcissable aux UV (HMPSA), le HMPSA comprenant : 1) un polymère acrylique durcissable aux UV qui est un produit de réaction d'un mélange réactionnel comprenant un ou plusieurs monomères acryliques et un ou plusieurs photo-initiateurs et 2) éventuellement un ou plusieurs composants supplémentaires, ledit polymère acrylique étant réticulable grâce auxdits groupes photo-initiateurs suite à son exposition à la lumière ultraviolette.
