             Rejection.  1                                                                                           

             THE INVENTION                                                                                           

                    The invention is directed to a radiation sensitive emulsion having maximum iodide                
             concentrations nearer the surface of the grain wherein the exterior portion of the grain                
             accounts for up to 15 percent of total silver.  The emulsion additionally contains specific             
             thiosulfonate and sulfinate compounds.  Additional limitations are provided in the following            
             illustrative claim.                                                                                     
                                                   THE CLAIMS

             below.                                                                                                  
             1.  A radiation sensitive emulsion comprised of a dispersing medium and silver                          
             iodochloride grains                                                                                     
                    WHEREIN the silver iodochloride grains                                                           
                    are cubical grains bounded by {100} crystal faces satisfying the orientation and                 
             spacing of cubic grains,                                                                                
                    contain from 0.05 to 1 mole percent iodide, based on total silver, with maximum                  
             iodide concentrations located nearer the surface of the grains than their center, comprise at           
             least one {111} crystal face,                                                                           
                    and wherein said emulsion further comprises a thiosulfonate of Formula I and a                   
             sulfinate of Formula II                                                                                 
                    wherein Formula I is                                                                             

                    1Claims 3 and 14 were cancelled in an amendment after Final Rejection received March 18 1996,    
             Paper No. 6 and entered by the examiner.
