Abstract

An ink composition that includes stearyl stearamide, N,N′-ethylene bisoleamide, at least one wax, at least one antioxidant, and at least one solvent dye colorant is useful as a phase change ink.

Claims

exact text as granted — not AI-modified
1 . An ink composition comprising:
 stearyl stearamide,   N,N′-ethylene bisoleamide,   at least one wax,   at least one antioxidant, and   at least one solvent dye colorant.   
     
     
         2 . The ink composition according to  claim 1 , wherein the at least one wax comprises a mixture of at least one Fischer-Tropsch wax and at least one fatty acid ester wax. 
     
     
         3 . The ink composition according to  claim 1 , wherein the at least one antioxidant is 
       
         
           
           
               
               
           
         
       
     
     
         4 . The ink composition according to  claim 2 , wherein the at least one antioxidant is 
       
         
           
           
               
               
           
         
       
     
     
         5 . The ink composition according to  claim 1 , wherein the at least one solvent dye colorant is solvent black. 
     
     
         6 . The ink composition according to  claim 2 , wherein the at least one solvent dye colorant is solvent black. 
     
     
         7 . The ink composition according to  claim 3 , wherein the at least one solvent dye colorant is solvent black. 
     
     
         8 . The ink composition according to  claim 1 , wherein the at least one solvent dye colorant is solvent yellow. 
     
     
         9 . The ink composition according to  claim 2 , wherein the at least one solvent dye colorant is solvent yellow. 
     
     
         10 . The ink composition according to  claim 3 , wherein the at least one solvent dye colorant is solvent yellow. 
     
     
         11 . A phase change ink composition comprising an ink vehicle and a colorant, wherein the phase change ink is solid at temperatures of from about 20° C. to about 27° C. and exhibits a viscosity of from about 1 to about 20 centipoise (cP) at an elevated temperature at which the phase change ink is to be jetted, wherein the ink vehicle comprises
 stearyl stearamide, 
 N,N′-ethylene bisoleamide, 
 at least one wax, and 
 at least one antioxidant, and wherein the colorant comprises at least one solvent dye colorant. 
 
     
     
         12 . The phase change ink composition according to  claim 11 , wherein the at least one wax comprises a mixture of at least one Fischer-Tropsch wax and at least one fatty acid ester wax. 
     
     
         13 . The phase change ink composition according to  claim 11 , wherein the at least one antioxidant is 
       
         
           
           
               
               
           
         
       
     
     
         14 . The phase change ink composition according to  claim 12 , wherein the at least one antioxidant is 
       
         
           
           
               
               
           
         
       
     
     
         15 . The phase change ink composition according to  claim 11 , wherein the at least one solvent dye colorant is solvent black. 
     
     
         16 . The phase change ink composition according to  claim 12 , wherein the at least one solvent dye colorant is solvent black. 
     
     
         17 . The phase change ink composition according to  claim 13 , wherein the at least one solvent dye colorant is solvent black. 
     
     
         18 . The phase change ink composition according to  claim 11 , wherein the at least one solvent dye colorant is solvent yellow. 
     
     
         19 . The phase change ink composition according to  claim 12 , wherein the at least one solvent dye colorant is solvent yellow. 
     
     
         20 . The phase change ink composition according to  claim 13 , wherein the at least one solvent dye colorant is solvent yellow.
