          Application No. 09/226,903                                                  

          containing coating compositions suitable for use as adhesives,              
          anti-flutter compositions, and coatings (e.g., for body panel               
          reinforcement and sound dampening).  (Specification, page 1,                
          lines 5-7.)  Further details of this appealed subject matter are            
          recited in representative claim 1, the only independent claim on            
          appeal, reproduced below:                                                   
                    1. A curable coating composition comprising:                      
                         (a)      at least one epoxy-functional                       
                                  polymer containing at least two                     
                                  epoxide groups per molecule present                 
                                  in an amount ranging from about 55                  
                                  to about 99 weight percent of total                 
                                  resin solids of the coating                         
                                  composition;                                        
                         (b)      at least one thermoplastic polymer                  
                                  which is substantially insoluble in                 
                                  the epoxy-functional polymer                        
                                  present in an amount ranging from                   
                                  about 1 to about 45 weight percent                  
                                  of total resin solids of the                        
                                  coating composition;                                
                         (c)      ground vulcanized rubber particles                  
                                  having an average particle size                     
                                  ranging from about 1 to about 300                   
                                  microns present in an amount                        
                                  ranging from about 1 to about 70                    
                                  weight percent of total resin                       
                                  solids of the coating composition;                  
                                  and                                                 
                         (d)      a curing agent adapted to cure the                  
                                  epoxy-functional polymer.                           
               The examiner relies on the following prior art references              
          as evidence of unpatentability:
