    Abstract: Adhesive tape rolls having detackified side faces are presented, and methods of their manufacture. In one embodiment, the method comprises applying one or more inks to a side face of an adhesive tape roll with an ink jet printing system. In some embodiments, inks are applied in an image-wise manner so as to create a pattern, text or graphics, which may include: barcodes. QR codes, brand information, manufacturing information, or remaining roll quantity indicia. In one aspect, the present methods enable elimination of packaging materials by two concurrent advantages: a) detackifying the side faces, which eliminates the need for packaging materials to prevent blocking of stacked rolls and accumulation of debris on side faces; and b) producing an adhesive tape roll bearing text, graphics, or other information on the side face of the roll, which eliminates the need for packaging materials to bear such information.

    Abstract: Debonding methods comprise: providing a bound article comprising, in order: a first adherend, a first primer layer, an adhesive layer, optionally a second primer layer, and a second adherend; heating the article to a release temperature; and separating the first and second adherends. At room temperature, the adhesive layer exhibits a high overlap shear of greater than 1.0 MPa (145 psi) or even greater than 5.0 MPa (725 psi), however, at release temperature, the adhesive layer exhibits an overlap shear of no more than 0.34 MPa (50 psi) or even no more than 0.21 MPa (30 psi). The release temperature may be a temperature between 100° C. and 150° C. The adhesive layer may comprise: a first film-forming polymer or oligomer; a cured polymer comprising a polymer of a first species comprising first unsaturated free-radically polymerizable groups; a first transition metal cation; and optionally a quaternary ammonium salt.
