Adhesive Articles Having Repositionability or Slidability Characteristics

Abstract

An adhesive article exhibiting air release or egress, repositionability, and/or slidability characteristics. An adhesive article comprises an adhesive layer comprising an adhesive surface comprising discrete forms of non-adhesive material randomly distributed on the patterned surface and at least partially embedded in the adhesive layer. The discrete forms of non-adhesive material provide areas of no or minimal adhesion and provide the article with some level of repositionability or slidability. The adhesive surface comprising the non-adhesive forms may be patterned to provide an adhesive surface with a contact surface and recessed area or channels that provide the article with a route for air to flow out from under the construction. An article may be formed by providing a release liner, applying discrete forms of non-adhesive material to a surface of the release liner, at least partially embedding the non-adhesive forms, and embossing the release liner.

What is claimed is: 
     
         1 . A pressure sensitive label, comprising:
 an adhesive layer having a first and second side;   a plurality of discrete non-adhesive material forms randomly distributed, each of the discrete non-adhesive material forms randomly located with respect to the other non-adhesive material forms and some of which are at least partially embedded in the adhesive layer;   a first release liner adhered to a first side of the adhesive layer;   a second release liner adhered to a second side of the adhesive layer;   wherein one of the first release liner or second release liner is used to transfer the label to a substrate; and   wherein both the first and second side of the adhesive layer include areas of non-adhesive material.   
     
     
         2 . A pressure sensitive label as recited in  claim 1 , wherein the release liner has a textured finish. 
     
     
         3 . A pressure sensitive label as recited in  claim 1 , wherein the release liner has a patterned finish. 
     
     
         4 . A pressure sensitive label as recited in  claim 1 , wherein the release liner is embossed by one of pressure rollers, a platen or a printing plate. 
     
     
         5 . A pressure sensitive label as recited in  claim 4 , wherein the embossing is accomplished at a pressure in the range of about 25 to about 150 pounds per square inch and a temperature of about 45 degree F. to about 300 degree F. 
     
     
         6 . A pressure sensitive label, comprising:
 an adhesive layer having a first and second side;   a plurality of discrete non-adhesive material forms randomly distributed each of the discrete non-adhesive material forms randomly located with respect to the other non-adhesive material forms and some of which are at least partially embedded in the adhesive layer;   a first release liner adhered to a first side of the adhesive layer, the first release liner having a first release surface and a first back surface;   a second release liner adhered to a second side of the adhesive layer; the second release liner having a second release surface and a second back surface;   wherein one of the first release liner or second release liner is used to transfer the label to a substrate; and   at least a portion of the non-adhesive material forms are exposed and lie above the plane of the first or second release surface; and   wherein both the first and second side of the adhesive layer include areas of non-adhesive material.   
     
     
         7 . The pressure sensitive label of  claim 1 , wherein the discrete non-adhesive material forms are random with to one or more of the following characteristics: size, shape, density, and configuration. 
     
     
         8 . The pressure sensitive label of  claim 1 , wherein the discrete non-adhesive material is an ink. 
     
     
         9 . The pressure sensitive label of  claim 1 , wherein the discrete non-adhesive material is an ultraviolet-curable ink. 
     
     
         10 . The pressure sensitive label of  claim 1 , wherein the discrete non-adhesive materials is an organic polymeric material.
