Abstract: Polymer dispersions in aqueous media form binders for pretreatments, coatings and images on substrates. The polymer includes polyamide segments and may have a high percentage of tertiary amide linkages, which facilitates film formation at temperature convenient to textiles and nonwovens. The polyamides are linked with reactions with polyisocyanates (which forms urea linkages if the other reactant is an amine or a urethane linkage if the other reactant is a hydroxyl group).

Abstract: Radiation curable ink compositions for impulse printheads are described. The compositions include a photoinitiator system, containing both a photocation polymerization initiator and a free-radical photoinitiator, an acrylate ester of a carboxylic acid ester, and at least one radiation curable material.

Abstract: Radiation curable and jettable ink compositions comprise ethylenically unsaturated oligomer and an ethylenically unsaturated monofunctional monomer. The compositions may optionally include additional ethylenically unsaturated polyfunctional component and/or chain transfer agent. The compositions have a viscosity at 25° C. of not greater than about 70 cPs and are radiation curable to form a cured ink having an elongation of at least 150%.

Abstract: The present invention is directed to radiation curable and jettable ink compositions and particularly to such compositions which exhibit enhanced elongation, when cured at low doses, and are advantageously used, for example, in digital inkjet printing. The compositions include a polyfunctional component and a monofunctional monomer, and may optionally include an additional monofuctional component and/or chain transfer agent. The compositions have a viscosity at 25° C. of not greater than about 70 cP and are radiation curable to form a cured ink having an elongation of between about 40 and about 150%. In addition, the compositions, when cured at low dose, exhibit a tack free surface and a low coefficient of friction.

Abstract: Disclosed herein are non-aqueous, radiation curable inkjet inks exhibiting stability at high shear rate (good rheological stability), stability at high temperatures, and/or stability in inkjet print heads, especially impulse inkjet print heads. The inks have a wide process window at a variety of print speeds using an impulse inkjet print head.
