Methods of producing ink toners and ink compositions including ink toners

A method of forming an ink toner comprising:

• mixing a carrier liquid and a resin to form a slurry;
• grinding the slurry for about 1 to 5 hours at about 50° C. to 60° C. at about 500 to 800 revolutions per minute (RPM);
• reducing the grinding to about 25 to 150 RPM;
• adding a pigment to the slurry and grind until the pigment is absorbed in the slurry to form a slurry/pigment mixture, wherein the pigment is selected from optically variable pigments, thermochromic pigments, photochromic pigments, photo luminescent pigments, phosphorescent pigments, electroluminescent pigments, and combinations thereof;
• and
• grinding the slurry/pigment mixture at about 500 to 800 RPM for about 15 to 45 minutes at about 25° C. to 35° C. to form the ink toner.
