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.
