            4          Newman relates generally to thermographic transfer sheets.  Col. 1,                        
            5   lines 4-9.                                                                                        
            6          Newman teaches, among other things, that CAB-O-SIL can be used as                          
            7   a filler to "reduce the tackiness" of a binder material.  Col. 3, lines 7-8.                      
            8          CAB-O-SIL is identified as having an average particle size of 0.012                        
            9   microns.  Col. 3, lines 10-11.                                                                    
          10           CAB-O-SIL is described as the preferred filler, but clay, titania,                         
          11    alumina, calcium carbonate, and talc are also said to be suitable.  Col. 3,                       
          12    lines -11-13

          17           In general Shultz relates to new and useful particulate NaAOS                              
          18    [sodium alpha olefin sulfonate] compositions adapted for use as an                                
          19    intermediate or concentrate in the preparation of particulate synthetic                           
          20    detergent formulations.  Col. 2, lines 59-64.

          23           One anti-tack agent is pyrogenic silica available commercially under                       
          24    the trademark CAB-O-SIL EH-5.  Col. 7, line 68 to col. 8, line 1.
