Abstract
Abstract A bookbinding tape having a substrate formed of a tough, flexible, scuff resistant high polymeric material and a low temperature reactivatable adhesive layer in which a coloring agent may be incorporated in the adhesive layer or in a separate layer between the adhesive layer and the substrate and indicia can be preprinted on the substrate beneath the adhesive layer and which can include a non-tacky layer on the adhesive layer to prevent blocking.
