          Appeal No. 1997-2070                                                        
          Application 08/487,921                                                      

          of the layer to the support and the coversheet.                             

               As explained in the specification at page 2, such a prior              
          art radiation sensitive recording material with a support;                  
          radiation sensitive layer; and coversheet has been utilized in              
          a process which involves removal of the coversheet, lamination              
          of the material to a substrate receptor; followed by imagewise              
          exposure of the material.  The support can be removed either                
          before or after exposure takes place.  A recurring problem                  
          with such prior art systems is the inability to separate the                
          coversheet cleanly from the radiation sensitive layer before                
          lamination to the receptor, because the adhesion between the                
          coversheet and the radiation sensitive layer is too high.  As               
          further indicated in the specification, a prior art solution                
          to this problem has involved the utilization of certain                     
          aliphatic polyesters which are added to the radiation                       
          sensitive layer to modify the adhesion balance.  Appellants'                
          invention involves the further improvement to such prior art                
          systems through the use of the claimed polydiorganosiloxane                 
          component in the tonable, radiation sensitive layer.  Thus the
