                     (ii) selecting a second resin having a glass transition temperature (T ) less than                    
                                                                                              g                            
              +20EC and a melt viscosity of 0.1 to 7 poise when measured at 180EC and at a sheer rate                      
              of 10,000 Hz, wherein at least one of said first and second resins is thermosettable,                        
                     (iii) dispersing a pigment in the first resin to form a pigmented first resin, and                    
                     (iv) combining the pigmented first resin and the second resin in proportions such                     
              that the glass transition temperature (T ) of the combined mixture of resins is greater than -               
                                                        g                                                                  
              30EC and less than +60EC, and such that the combined mixture of resins has a melt                            
              viscosity of about 0.1 to 12 poise when measured at 180EC and at a shear rate of 10,000                      
              Hz to thereby form said solventless paint composition.                                                       
              The references relied upon by the examiner are:

                                                 Ground of Rejection                                                       

                     Claims 5-7, 9-11, 13-15, 17-48, and 50-69 stand rejected under 35 U.S.C.  103.                       
              As evidence of obviousness, the examiner relies upon Pettit, Grenfell and Wallace.                           
                     We reverse.

                     The applicants' invention, as described at page 3 of the specification, is directed  to               
              a solventless coating composition which can be applied as a hot melt and which avoids or                     
              at least ameliorates the disadvantages of coatings of the prior art.
