    摘要: An aqueous jet ink of water, dissolved dyes and a surfactant of R--N(C.sub.2 H.sub.4 O).sub.x (C.sub.2 H.sub.4 O).sub.y H, where x+y is from 5 to 25, with x and y each at least 2, and R is alkyl or oxygen containing. The static surface tension is less than 40 dynes/cm while the dynamic surface tension is about 65 dynes/cm. Satellites and splatter in thermal drop on demand printing are greatly reduced, and drop misdirection is reduced.

    摘要: A water-soluble dye for a color subtractive, lightfast, wide spectrum ink as follows: ##STR1## wherein: X is ##STR2## R.sub.1 is: an aliphatic radical having from 1 to 18 carbon atoms; the radical ##STR3## in which R.sub.2 is --H, -lower alkyl of 1 to 4 C atoms, -lower alkoxy, -halogen, --NO.sub.2 --CN, --CO.sub.2 H;R.sub.3 is --H, -lower alkyl having 1 to 4 C atoms, -halogen, --CO.sub.2 H;M is H, Li, Na, K, --N(R.sub.4).sub.4 in which R.sub.4 is H, ##STR4## in which R.sub.5 is --H, -lower alkyl, and.sub.n is 1 to 4; and in which one of the --SO.sub.3 M groups on the amino-naphthol radical is positioned meta or para --SO.sub.3 M is meta to the --OH.and the dye in a water and glycol vehicle. A dye set of this dye, Direct Blue 199, and Direct Yellow 132 provides a full color spectrum of bright, lightfast colors.
