Pressure-sensitive adhesive tape having a substantially tack-free surface |
| abstract |
40698 CAN lA Abstract of the Disclosure A pressure-sensitive adhesive layer is crosslinked between carboxyl groups along one surface by polyvalent cations, thus making that surface substantially tack-free while leaving at least one broad surface of the layer tacky and pressure-sensitive. When a broad surface of the adhesive layer is thus made completely tack-free, the adhesive layer can be wound upon itself in roll form without a backing for convenient storage and shipment. Preferably a low-adhesion backsize coating covers the broad tack-free surface to insure that the adhesive layer can be unwound after prolonged storage without delaminating. |
