          Application 08/417,290                                                      




                                    THE INVENTION                                     
               Appellants’ claimed invention is directed toward a                     
          conditioning solution which contains, as an antimicrobial                   
          agent, a polyaminocarboxylic acid or salt thereof which has a               
          recited general formula and is present in a specified                       
          concentration.  Appellants state that the conditioning                      
          solution is useful in the processing of color photographic                  
          materials (specification, page 1, lines 6-10).  Claim 1 is                  
          illustrative and reads as follows:                                          
               1.  A conditioning solution having a pH of from about 4.5              
          to about 8, and comprising a bleach accelerating agent, a                   
          formaldehyde precursor, and an antimicrobial composition                    
          consisting essentially of a polyaminocarboxylic acid or salt                
          thereof as the sole antimicrobial agent, said antimicrobial                 
          agent being present in said conditioning solution in an amount              
          of from                                  about 0.25 to about 3              
          g/1,                                                                        
                                                   said                               
          polyamin                                 ocarboxylic acid or                
          salt                                     thereof being                      
          represen                                 ted by formula II:
