摘要： Disclosed is an ink composition comprising water, a colorant, and sodium tetraphenylboride. Another embodiment of the present invention is directed to a set of inks for printing multicolor images in an ink jet printer, the ink set comprising (1) a first ink having a first color and comprising water, a first colorant, and at least one of (a) a cationic polymer, (b) a cationic surfactant, or (c) an inorganic salt the cation of which has a tetraphenylboride salt that is substantially insoluble in water, and (2) a second ink having a second color different from the first color and comprising water, a second colorant, and sodium tetraphenylboride, wherein intercolor bleed between the first ink and the second ink is reduced when the second ink is printed adjacent to, on top of, or underneath the first ink on a print substrate.

摘要： Process for producing a corrosion-resistant liquid level control plate for the printhead of an aqueous ink jet printing machine. A corrosion-resistant metal alloy base is used, having an undersurface and an upper surface and having closely-spaced ink jet nozzles therethrough. Each of the nozzles has a micro-orifice at the undersurface surrounded by a lip area at the bottom of upwardly and outwardly tapered walls opening at the upper surface. The present process comprises forming the lip areas of metallic gold, encapsulating the upper surface of the metal alloy base including the gold lip areas and the tapered walls with metallic gold to form a corrosion-resistant, hydrophobic surface layer thereover. Thereafter the undersurface is coated with metallic chromium to render it hydrophilic. The gold coating preferably is reacted with a self assembled monolayer (SAM) of an organic sulfur compound such as hexadecylthiol or, more preferably, a cross-linkable SAM which is then cross-linked in situ to form a rub-resistant layer having strong hydrophobic properties. The chrome coating on the undersurface may be coated with a hydrophilic silane to increase its hydrophilic properties.
