                      a substantially contact transparent backing comprising first and                       
                second major surfaces;                                                                       
                      a first pressure sensitive adhesive; and                                               
                      a second pressure sensitive adhesive;                                                  
                      wherein the first pressure sensitive adhesive is located on substantially              
                all of the first major surface of the backing and the second pressure sensitive              
                adhesive is located on a portion of the first pressure sensitive adhesive;                   
                whereby substantially all of the second pressure sensitive adhesive is                       
                exposed on the medical dressing and only a portion of the first pressure                     
                sensitive adhesive is exposed on the medical dressing;                                       
                      and further wherein the first pressure sensitive adhesive has a higher                 
                tack to skin than the second pressure sensitive adhesive.                                    
                66. The medical dressing of claim 65, wherein the second pressure                            
                sensitive adhesive comprises at least one bioactive agent.                                   
                77. A medical dressing comprising:                                                           
                      a substantially contact transparent backing comprising first and                       
                second major surfaces;                                                                       
                      a first pressure sensitive adhesive located directly on a portion of the               
                first major surface of the backing, wherein at least a portion of the first                  
                pressure sensitive adhesive is exposed on the first major surface of the                     
                backing; and                                                                                 
                      a second pressure sensitive adhesive located directly on a portion of                  
                the first major surface of the backing,                                                      
                      wherein the first pressure sensitive adhesive forms a border around the                
                second pressure sensitive adhesive on the first major surface of the backing,                
                and further wherein the first pressure sensitive adhesive has a higher tack to               
                skin than the second pressure sensitive adhesive.                                            
                78. The medical dressing of claim 77, wherein the second pressure                            
                sensitive adhesive comprises at least one bioactive agent.
