CA 2256723

A method for the modification of the surface of a pressure-sensitive adhesive with a functional group whereby a functional group effective in improving and regulating the adhesion can be densely and stably introduced into the surface of a pressure-sensitive adhesive. In this method, a functional group is immobilized onto the surface of a pressure- sensitive adhesive by an interfacial catalytic reaction of a pressure-sensitive adhesive phase with a phase containing a functional group- containing compound.

La présente invention concerne un procédé de modification superficielle d'un adhésif autocollant au moyen d'un groupe fonctionnel. Ce procédé consiste à utiliser un groupe fonctionnel qui est capable d'améliorer et de réguler l'adhésion et que l'on peut introduire de façon dense et stable dans la surface d'un adhésif autocollant. En l'occurrence, on immobilise un groupe fonctionnel sur la surface d'un adhésif autocollant au moyen d'une réaction catalytique à l'interface entre une phase autocollante et une phase à base d'un composé contenant le groupe fonctionnel.
