description A heat shrinkable label comprises (A) a heat shrinkable film comprising at least one thermoplastic polymer, and (B) a curable adhesive comprising (1) at least one urethane (meth)acrylate resin having an average of about 1 to about 1.6 (meth)acrylate groups per resin molecule, (2) at least one tackifier, and (3) at least one photoinitiator, where the film has an ultimate shrinkage at 135°C of at least 15%, and the adhesive has sufficient precure tack, wherein the loop tack of the uncured adhesive is at least 4.3 g/cm2. The heat shrinkable label is useful in high-speed industrial processes such as beverage container labeling. Etiquette thermorétrécissante composée (A) d'une pellicule thermorétrécissante comprenant au moins un polymère thermoplastique et (B) d'un adhésif durcissant comprenant (1) au moins une résine d'uréthane méthacrylate comportant en moyenne 1 à 1,6 groupes méthacrylate par molécule de résine, (2) au moins un agent collant et (3) au moins un photodéclencheur, cette pellicule présentant un rétrécissement ultime à 135 °C d'au moins 15 %, l'adhésif étant suffisamment collant avant durcissement et la pégosité de l'adhésif non durci étant d'au moins 4,3 g/cm2. Cette étiquette thermorétrécissante est utile dans des processus industriels très rapides, tels que l'étiquetage de réservoirs de boisson.
