Appl. No.:

10/134880

Illinois Tool Works, Inc. - Glenview IL

International Classification:

C09D 11/10
B41J 2/04

US Classification:

523160, 347 54, 106 3185, 106 3186

Abstract:

Impulse ink jet compositions are provided which are suitable for printing clear, well-defined alphanumeric text or low spread, narrow bar width bar codes on porous substrates such as Kraft paper or corrugated cardboard. The inks may also contain an antioxidant that lowers the dissolved oxygen level in the ink, thereby enhancing the jetting performance of the printhead.

International Classification:

B41J002/19

US Classification:

347/092000

Abstract:

Methods for reducing cavitation in impulse or drop on demand ink jetting devices are provided. Impulse ink jet compositions comprising antioxidant are also provided which are suitable for printing clear, well-defined alphanumeric text or low spread, narrow bar width bar codes on porous substrates such as Kraft paper or corrugated cardboard. The antioxidant additive lowers the dissolved oxygen level in the ink, thereby enhancing the jetting performance of the printhead.

Illinois Tool Works Inc. - Glenview IL

International Classification:

C03C 17/00

US Classification:

523160000, 524379000

Abstract:

The present invention provides improved performance inks for use in an impulse inkjet printer. The fast-drying compositions comprise from about 40 to about 55 percent by weight of a glycol alkyl ether having about 3 to 20 carbon atoms, about 30 to about 40 percent by weight of a solvent that is a ketone alcohol, 1,4-butanediol, ethanol, benzyl alcohol, alkyl lactates, or mixtures thereof; about 1 to about 10 percent by weight of glycerol; about 0.5 to about 5 percent by weight of a polymeric resin; about 0.5 to about 2 percent of one or more of surface modifiers and antioxidants; and about 1 to about 20 percent by weight of a colorant.

Abstract:

A process for printing on a textile substrate comprising the steps of: (I) preparing an ink comprising the following components: (a) from 1 to 8 parts of a self-dispersible pigment which comprises a carboxy-functional dispersant crosslinked around a pigment core by a crosslinking agent having at least two groups selected from oxetane, carbodiimide, hydrazide, oxazoline, aziridine, isocyanate, N-methylol, keteneimine, isocyanurate and epoxy groups; (b) from 0 to 16 parts of a binder selected from one or more of an acrylic latex binder, a styrene acrylic latex binder and a styrene butadiene latex binder wherein the binder has a Tg in the range of from −25 C. to 35 C.; (c) from 1 to 30 parts of one or more water-miscible organic solvents (d) from 0.1 to 3 parts of a surfactant; (e) from 0 to 5 parts of biocide; (f) from 0 to 10 parts of a viscosity modifier; (g) from 0 to 10 parts of a polyurethane latex binder with a Tg in the range of from −25 C. to 35 C.; (h) from 0 to 6 parts of a cross linking agent; and (i) the balance to 100 parts water: (II) optionally preparing a latex binders solution comprising; i) from 1 to 16 parts of one or more latex binders selected from an acrylic latex binder, a styrene acrylic latex binder and a styrene butadiene latex binder where the latex binder(s) have a Tg in the range of from −25 C. to 35 C.; ii) from 0 to 6 parts of a polyurethane latex binder; and iii) from 0 to 5 parts of a cross linking agent: (III) printing the ink prepared in step (I) on to a textile substrate using a ink jet printer with a single pass print head and optionally pre-printing or overprinting with the latex binder solution from step (II) (IV) curing the printed textile substrate from step (III): provided that if component (b) in the ink prepared in step (a) is 0 then optional step (II) is compulsory. Also inks, ink-sets, ink containers and ink-jet printers.
