CA 2200060

The present invention is directed toward a multilayer, pressure-sensitive adhesive construction wherein one layer is formed of a first adhesive composition having a first glass transition temperature, and at least a second layer is formed of a second adhesive composition having a second glass transition temperature. The first glass transition temperature differs from the second glass transition temperature.

L'invention porte sur une structure adhésive autocollante multicouche dont l'une des couches se compose d'une première composition adhésive présentant une première température de transition vitreuse, et dont au moins une seconde couche se compose d'une deuxième composition adhésive présentant une deuxième température de transition vitreuse, la première température de transition vitreuse différant de la deuxième d'environ 10 ~C à environ 50 ~C.
