Abstract

1359350 Ink composition A B DICK CO 7 Dec 1971 [7 Dec 1970] 56847/71 Heading C3R [Also in Division C4] An ink comprises an aqueous solution of 0À5-7À0% by wt. of a water-soluble direct dye and 5-40% of a humectant consisting of (a) a C 1 -C 6 alkoxy triglycol and (b) polyethylene glycol of M.W. not more than 600 or polypropylene glycol of M.W. not more than 425, (b) and (a) being in a weight ratio of 0À1- 30 : 1, and the composition having a viscosity at 25‹ C. of 1-10 cp., and a specific resistivity less than 150 ohm-cm. The triglycol may be methoxy or ethoxy triethylene glycol, and the ink may also contain a base to maintain the pH above 9, a solubilizer for the dye(s), and a preservative. Examples 1-3, 5, 6, 9 are directed to inks containing 4À5-6% by wt. polyethylene glycol of M.W. 200, and Ex. 4, to an ink with 4À5% polyethylene glycol of M.W. 400, the other ingredients including black dyes, monoethanolamine to control pH, N-methyl-2- pyrrolidone as a dye solubilizer, and "Dioxin" (R.T.M. - 6 - acetoxy - 2,4 - dimethyl - mdioxane) preservative.
