    摘要: An ink refill device includes a body having a chamber with ink therein. The chamber has one wall formed of a frangible material. The body has a needle communicating the chamber with a reservoir, which has a foam of a controlled porosity therein, in a print cartridge when the needle is inserted in a vent of the reservoir to fill the reservoir. Breaking of the frangible wall of the chamber with the needle extending downwardly enables ink to flow from the chamber at a controlled flow rate to the reservoir in the cartridge. In the preferred embodiment, the needle has one or more notched openings adjacent its distal end to increase its surface area through which ink flows to increase flow of ink to the reservoir.

    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.
