20140347429 | Inks - An ink comprising a colorant, an organic solvent having a boiling point below 170° C. and a radiation-curable component of molecular weight >1000, wherein the ink contains less than 10 wt % of radiation-curable components of molecular weight 1000 or less and the ink contains less than 5 wt % water. The ink is particularly useful for printing packaging used for products intended for ingestion by humans or other animals. | 11-27-2014 |
20140313267 | PRINTING INK, APPARATUS AND METHOD - The present invention provides an inkjet ink comprising at least 30% by weight of organic solvent based on the total weight of the ink, a radiation curable material, a photoinitiator and optionally a colourant. The invention also provides an apparatus for printing the ink wherein the apparatus comprises at least one printhead, a means for evaporating solvent from the printed ink and a source of actinic radiation. Furthermore, the invention provides a method of inkjet printing comprising i) inkjet printing the inkjet ink as defined above on to a substrate; ii) evaporating at least a portion of the solvent from the printed ink; and iii) exposing the printed ink to actinic radiation to cure the radiation curable material. | 10-23-2014 |
20140063154 | INK-JET PRINTING METHOD - The present invention provides a method of inkjet printing comprising the following steps, in order: (i) providing a hybrid inkjet ink comprising an organic solvent, a radiation-curable material, a photoinitiator and optionally a colorant; (ii) printing the ink on to a substrate; (iii) pinning the ink by exposing the ink to actinic radiation at a dose of 1-200 mJ/cm | 03-06-2014 |
20130127963 | Printing Ink - This invention relates to a radiation-curable ink-jet ink having a viscosity of 30 mPas or less at 25° C., the ink comprising: at least two monofunctional (meth)acrylate monomers which comprise a cyclic monofunctional (meth)acrylate monomer and 2-(2-ethoxyethoxy)ethyl acrylate; a monofunctional monomer selected from an N-vinyl amide, and N-acryloyl amine or a mixture thereof; a multifunctional (meth)acrylate monomer; a polymerisable (meth)acrylate oligomer; a radical photoinitiator; and a colouring agent. The ink is preferably used in reel-to-reel printing and in printing where the substrates are stacked. | 05-23-2013 |
20120208915 | PRINTING INK - The present invention provides a colourless inkjet ink composition comprising at least 30% by weight of mono-functional acrylate monomer based on the total weight of the ink and at least 3% by weight of a photoinitiator based on the total weight of the ink, wherein the photoinitiator comprises an α-hydroxy ketone photoinitiator and wherein the ink comprises 0 to 6% by weight of acyl phosphine photoinitiator based on the total weight of the ink. | 08-16-2012 |
20120207985 | PRINTING INK - The present invention provides an inkjet ink comprising 5 to 30% by weight of organic solvent based on the total weight of the ink, a radiation curable monofunctional monomer, a radiation curable multifunctional monomer, a photoinitiator and a colourant. | 08-16-2012 |
20120206534 | PRINTING INK, APPARATUS AND METHOD - The present invention provides an inkjet ink comprising at least 30% by weight of organic solvent based on the total weight of the ink, a radiation curable material, a photoinitiator and optionally a colourant. The invention also provides an apparatus for printing the ink wherein the apparatus comprises at least one printhead, a means for evaporating solvent from the printed ink and a source of actinic radiation. Furthermore, the invention provides a method of inkjet printing comprising i) inkjet printing the inkjet ink as defined above on to a substrate; ii) evaporating at least a portion of the solvent from the printed ink; and iii) exposing the printed ink to actinic radiation to cure the radiation curable material. | 08-16-2012 |
20120126931 | ELECTROLYTE COMPOSITION - This invention relates to an electrolyte composition comprising an ionic liquid, a gellant selected from a cellulose derivative, gelatine and combinations thereof, and a radiation-curabie base. It also provides an electrochemical device comprising the electrolyte composition | 05-24-2012 |
20100309269 | CURING - A method of curing radiation-curable fluid is described. In one example, the method includes emitting radiation from an array of light-emitting diodes towards ink to be cured. LEDs are cheap, light weight, highly efficient in their conversion of electrical power, and give effectively instant switching to full power. Another advantage is that the emission spectrum of an LED is sharply peaked around the nominal frequency. Thus LEDs give several advantages over conventional radiation sources such as mercury lamps. A low oxygen environment is preferably provided at the radiation source to accelerate the curing reaction. Also described are inks which are specially formulated to respond to the radiation emission spectrum of an LED. | 12-09-2010 |
