  • Ink compositions for thermal ink jet printing
    Patent number: 5772743
    Abstract: Disclosed is an ink composition which comprises (a) water, (b) a colorant, (c) a fluorinated material selected from: (1) those of the formula ?(F.sub.2n+1 C.sub.n CH.sub.2 S).sub.2 (CH.sub.3)C--CH.sub.2 CH.sub.2 COO.sup.- !?B.sup.+ !, wherein n is an integer of from about 8 to about 20 and B is a cation, (2) those of the formula ?(F.sub.3 C(F.sub.2 C).sub.n CH.dbd.CHCH.sub.2 OCH(OH)CH.sub.2).sub.2 NCH.sub.2 COO.sup.- !?X.sup.+ !, wherein X is a cation and n is an integer of from about 3 to about 20, and (3) mixtures thereof, and (d) a monomeric compound having at least two carboxylic acid functional groups. Also disclosed is a process for preparing said ink composition which comprises (i) admixing the ink ingredients, and (ii) subjecting the mixture thus formed to ultrasonification, thereby reducing the average particle diameter of liposomes of the fluorinated material in the ink.
