The present invention provides ink-jet inks and methods for increasing slewing time of an ink-jet ink pen without significant decap. The composition can comprise an effective amount of a dye, an effective amount of an ink vehicle, and an effective amount of an anti-slewing decap agent comprising an alkyl aryl sulfonamide. In one embodiment, the anti-slewing decap agent consists essentially of the alkyl aryl sulfonamide. With regard to the method, the steps can including formulating the composition; loading the ink-jet ink in an ink-jet pen; and configuring the ink-jet pen to allow for increased slewing time between firing. Additionally, a system of printing high quality images with reduced slewing decap can comprise an ink-jet ink pen configured for firing non-image producing spits at from 3 and 6 second intervals, an ink-jet ink composition having an effective amount of an alkyl aryl sulfonamide present, and a substrate for accepting the ink-jet ink composition such that the high quality image is formed.

摘要:
An ink obtained by dissolving at least one specific dye in an aqueous medium, wherein the dyes contained in the ink all have a solubility of 15 g or more in 100 g of water at 25null C. under atmospheric pressure; and an ink set formed from the ink. The dye is preferably a dye having an oxidation potential of 1.0 V (vs SCE) or more, more preferably a specific azo dye having a heterocyclic group of a specific structure or an aromatic group which is bound directly to an azo group, or a specific phthalocyanine dye having a water-soluble group as a substitunet. According to the present invention, an ink, specifically an inkjet ink, and an ink set, which can print an image without disorder or beading due to ejection failure and ensure excellent ejection stability and durability, is provided.
