Abstract
Abstract An adhesive label comprising, in order, a printing carrier, a primer on the back of the printing carrier, an adhesion layer, a covering layer, and an optional adhesive-repellent layer between the adhesion layer and the cover layer. The primer comprises isocyanate-terminated compounds, particularly isocyanate-terminated polyurethanes. The adhesive label is made by applying the adhesion layer to the covering layer or to the optional adhesive-repellent layer on the covering layer, and combining the adhesion layer and a stratum made from the printing carrier and the primer by applying the adhesion layer onto the primer.
