Ink Jet Ink

The use of a fluorosurfactant as the only surface-wetting agent of an aqueous-based ink jet ink produces an ink which is capable of high quality printing on both absorptive and nonabsorptive substrates.

Ink which is used to print on smooth, nonabsorptive substrates, such as plastic or metal, must generally have low surface tension, for example, less than 35 dynes/cm. However, this low surface tension characteristic usually causes the ink to excessively penetrate absorptive substrates, such as paper, undesirably producing indistinct printed characters.

The use of a fluorosurfactant, such as Z0NYL* FSB, produces an ink capable of high quality printing on a wide variety of substrates. Nonionic, cationic or anionic fluorosurfactants can also be used.

A water-based ink jet ink, containing Z0NYL FSB, which produces high quality printing on both absorptive and nonabsorptive substrates is of the following formulation: Percent by Weight Dye 5.4 Acrylic Binder 10.0 Polyethylene Glycol 6.0 Chelating Agent 0.2 Biocide 0.1 ZONYL FSB 0.1 Ammonium Hydroxide (28%) 2.5 Water 75.7 * Trademark of E. I. du Pont de Nemours & Co.
