             Appeal No. 95-0442                                                                                   
             Application 08/026,183                                                                               

             to about 3500 (col. 2, lines 36-38), and the carboxyl group-                                         
             containing butadiene-acrylonitrile rubber preferably is carboxyl                                     
             terminated (col. 2, lines 50-52).  The rubber-modified epoxy                                         
             resin generally has an epoxy equivalent of 200 to 5000,                                              
             preferably 250-4000 (col. 3, lines 38-41), and the rubber                                            
             component is about 5-35 wt% of this resin (col. 3, lines 9-10).                                      
             The disclosed curing agents include dicyandiamide type curing                                        
             agents, hydrazide type curing agents, and imidazole type curing                                      
             agents (col. 4, lines 25-31).  The composition can include, in                                       
             combination with the rubber-modified epoxy resin, an epoxy resin                                     
             which can be any epoxy resin which is useful for making the                                          
             rubber-modified epoxy resin (col. 3, lines 3-10).  The                                               
             composition also can include various additives, including a                                          
             filler such as silica, depending upon the intended use and                                           
             desired properties of the composition (col. 5, lines 8-19).                                          
                    Appellants argue that there is no teaching in Yamamoto which                                  
             would have motivated one of ordinary skill in the art to delete                                      
             the organic solvent, metal powder and phenoxy resin from                                             
             Yamamoto’s composition (brief, pages 6 and 8-10).  We do not                                         
             consider this argument to be well taken as to the organic solvent                                    
             and metal powder components.                                                                         
                    Yamamoto teaches that it was known in the art to use epoxy
