Abstract
The present invention provides improved performance inks for use in an impulse inkjet printer. The fast-drying compositions comprise from about 40 to about 55 percent by weight of a glycol alkyl ether having about 3 to 20 carbon atoms, about 30 to about 40 percent by weight of a solvent that is a ketone alcohol, 1,4-butanediol, ethanol, benzyl alcohol, alkyl lactates, or mixtures thereof; about 1 to about 10 percent by weight of glycerol; about 0.5 to about 5 percent by weight of a polymeric resin; about 0.5 to about 2 percent of one or more of surface modifiers and antioxidants; and about 1 to about 20 percent by weight of a colorant.
Claims20
A fast drying ink composition, for use in impulse inkjet printers, comprising:
- about 40 to about 55 percent by weight of at least one glycol alkyl ether having about 3 to about 20 carbon atoms,
- about 30 to about 40 percent by weight of a ketone alcohol, 1,4-butanediol, ethanol, benzyl alcohol, alkyl lactates, carbitol, or mixtures thereof;
- about 1 to about 10 percent by weight of glycerol
- about 0.5 to about 5 percent by weight of a polymeric resin;
- about 0.5 to about 2 percent of one or more of surface modifiers and antioxidants;
- and
- about 1 to about 20 percent by weight of a colorant.
A method of operating an impulse inkjet printer having at least one nozzle comprising ejecting ink from said nozzle onto a substrate, said ink comprising:
- about 40 to about 55 percent by weight of at least one glycol alkyl ether having about 3 to about 20 carbon atoms,
- about 30 to about 40 percent by weight of a ketone alcohol, 1,4-butanediol, ethanol, benzyl alcohol, alkyl lactates, carbitol, or mixtures thereof;
- about 1 to about 10 percent by weight of glycerol;
- about 0.5 to about 5 percent by weight of a polymeric resin;
- about 0.5 to about 2 percent of a surface modifier;
- and
- about 1 to about 20 percent by weight of a colorant.
