ABSTRACT:
A HAPs-free ink jet ink includes a pigment; a binder comprising vinyl chloride-vinyl acetate copolymer; and a HAPs-free solvent component comprising 1-methoxy-2-propanol acetate, a dispersing solvent selected from cyclohexanone, n-propyl acetate, n-butyl acetate, diisobutyl ketone, isobutyl acetate, amyl acetate, and combinations of these, and a diluent solvent selected from dipropylene glycol methyl ether, dipropylene glycol methyl ether acetate, tripropylene glycol methyl ether, ethylene glycol diacetate, propylene glycol n-butyl ether, propylene glycol n-propyl ether, and combinations of these. The ink has excellent stability and printing properties. Printing with the ink avoids release of HAPs while allowing long print runs with low maintenance.
