          Appeal No. 96-1675                                                           
          Application No. 08/317,977                                                   

          solution including a buffer and a hydrogen peroxide at a pH of               
          11.0.                                                                        
               Iwano discloses an aqueous monobath development-                        
          intensifying solution containing hydrogen peroxide or a                      
          compound which releases hydrogen peroxide and a color                        
          developing agent (column 3, lines 9 through 23; column 5,                    
          lines 64 through 68).  The aqueous solution may be used in any               
          one of known systems useful for performing monobath type                     
          color-intensifying processing (column 4, lines 49 through 54)                
          and include coating development methods where a first solution               
          containing a color-developing agent and second solution                      
          containing hydrogen peroxide or a compound which releases                    
          hydrogen peroxide may be used separately successively or the                 
          first and second solutions may be mixed to form a single                     
          solution followed by application of the single solution                      
          (column 5, lines 21 through 29).  The pH of the monobath                     
          development-intensifying solution is 9 or higher, preferably                 
          from 10 to 12 (column 5, lines 61 through 63).  Hydroxylamine                
          sulfate is disclosed as an additive which may be further                     
          included in the development-intensifier solution (column 12,                 
          lines 3 through 5). A variety of other additives may be
