ABSTRACT:
Adhesive products such as label stock, labels, tapes, and the like having a facestock, an adhesive layer and a removable, fibrous backing are described. The backing is provided with integral embrittled zones which crack when the adhesive product is flexed and offer gripping points for removal of the backing. The embrittled zones contain brittle, film-forming organic polymer suffused among the fibers. The presence of the polymer in the embrittled zone helps to enhance the brittleness of the zones and to reduce the transfer of residual chemical embrittling agent from embrittled zones of the backing to portions of the facestock brought into contact therewith when the adhesive product is stacked or rolled. Embrittled zones are preferably formed by applying a thickened acidic solution comprising a polymer emulsion to the backing of the adhesive product and then curing and drying the solution by heating.
