Abstract
This invention is directed to a pressure sensitive positioning adhesive for absorbent articles which can be used without release paper. The positioning adhesive has non-tacky irregularly shaped particles on its surface thereby rendering the adhesive non-tacky. Upon the application of pressure during use, i.e., when attaching the napkin to the undergarment, the particles are rearranged, exposing adhesive to the undergarment, thereby facilitating attachment of the napkin to the undergarment.
