    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: The present disclosure provides multilayer stacks that can be used as decorative microsphere articles. The decorative microsphere articles can be a durable and aesthetically pleasing substitute for anodized aluminum and other matte metallic surfaces. The decorative microsphere articles are durable and can have a bright diffused appearance of any desired color, for example white, gold, silver, red, or other colors, while being capable of being manufactured using a roll-to-roll process. The decorative microsphere articles can also provide novel optical effects than can change at different viewing angles, including, for example, changing color with view angle, changing sharpness or clarity of an image or icon with view angle, and the like, that may allow customers to differentiate their products.

    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 100ºC and 150ºC. 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.
