Inkjet inks are described that have, as a principal component, a crosslinked polyurethane dispersoid binder additive. These inks can be used for printing on different media, and are particularly suitable for printing on textiles.

Inkjet inks containing crosslinked polyurethanes

Linear block copolymers that have at least one hydrophilic block and at least one hydrophobic block, wherein the hydrophilic block of the copolymer has at least one carboxylic acid functionality (or salt thereof) that can readily decarboxylate. These copolymers are useful as binders and/or dispersants in inkjet inks.

Decarboxylating block copolymers

An ink set is provided which produces a printed article having excellent physical durability. The ink set contains a first liquid composition containing a reactive carbonyl group and a second liquid composition containing a co-reactive amine group, at least one of the first liquid composition and the second liquid composition further containing a coloring material. When the two inks are printed on a substrate in at least a partially overlapping arrangement, the reactive amine and reactive carbonyl species can crosslink to form a more durable image.

Inkjet ink set

Method for printing high gloss, high DOI (distinctness of image) images with pigmented inkjet inks. The method comprises printing the pigmented inks in one pass onto absorbent glossy media.

Inkjet printing with pigmented inks

The present invention pertains to a substantially colorless, oxysilyl groups-containing fixer fluid which, when applied over or under an inkjet ink, can enhance the properties of a printed image. The invention also pertains to an ink set comprising the fixer fluid, and a printing method employing the ink set.

Fixing fluid and inkjet ink sets comprising same

This invention pertains to an inkjet ink comprising a polyazetidinium groups-containing component, various ink sets comprising this ink, including one ink set with at least one co-reactive ink, and a method of printing with the ink and ink sets. When the inks are printed onto a substrate, the polyazetidinium groups can chemically react to enhance the durability of the printed image.

Inkjet ink, ink set and method of printing

This invention pertains to an inkjet ink including a polycarbodiimide groups-containing component, various ink sets comprising this ink, including one ink set with at least one co-reactive ink, and a method of printing with the ink and ink sets. When the inks are printed onto a substrate, the polycarbodiimide groups can chemically react to enhance the durability of the printed image.

The present invention pertains to a dye-based inkjet ink set and, more particularly, to an ink set with at least six differently colored inks. The ink set includes at least a cyan, magenta, yellow, red, blue and green ink.

Inkjet ink set for improved color reproduction

The present invention pertains to a pigment based inkjet ink and ink set. More particularly the invention pertains to an ink that is red, green or blue in color comprised of certain pigment combinations. The invention further pertains to an ink set comprised of at least one red, green or blue ink and most preferably to an ink set with at least six differently colored inks that includes a cyan, magenta, yellow, red, blue and green ink.

Pigmented inkjet ink and ink set

The invention relates to an ink jet ink composition containing monodisperse polymer particles to provide an opaque ink with improved color brilliancy, ink jet ink sets based on this composition, and a methods for ink jet printing with the ink and/or ink jet sets.

Ink jet ink composition

This invention pertains to an ink set for inkjet printing, in particular to an ink set comprising at least one ink comprising colorant and nonaqueous vehicle; and

Inkjet ink set and method of using same

This invention pertains to an ink set for inkjet printing, in particular to an ink set wherein all the inks are mutually interactive so as to reduce bleed of one color into another. The invention also pertains to a method of inkjet printing with this mutually interactive ink set.

Interactive ink set for inkjet printing

An automated handling apparatus for testing and labeling a printed circuit board. The apparatus comprises a housing having at least one tray exchanger assembly attached thereto. Disposed on the tray exchanger assembly is a cassette tray which accommodates at least one circuit board, and is selectively movable between first and second positions by the tray exchanger assembly. Also attached to the housing is a testing assembly for conducting a desired testing protocol upon the circuit board, a labeler assembly for applying a label to the circuit board subsequent to the completion of the testing protocol, and a loader assembly for selectively transporting the circuit board between the tray exchanger, testing, and labeling assemblies.

Automated circuit board testing apparatus

Aqueous, fluorescent red ink jet inks which meet US Postal Service requirements for metered mail are disclosed and comprise an aqueous vehicle, a red or magenta pigment, a polymeric dispersant, a fluorescent dye and, optionally a hydrotrope additive.

Aqueous ink jet inks for postal metering

Excellent resolution and sensitivity in the patterning of resists utilized in device and mask manufacture is obtained with a specific composition. In particular this composition involves polymers having recurring pendant acid labile .alpha.-alkoxyalkyl carboxylic acid ester and/or hydroxyaromatic ether moieties in the presence of a substance that is an acid generator upon exposure to actinic radiation.
