Ink composition for a meltable ink and a method of printing a substrate with such an ink composition
Patent number: 6471758Abstract: An ink composition for a meltable ink usable in a printing device in which ink drops are ejected from ink ducts, which comprises agents which reversibly cross-link the ink, the said agents containing a gelling agent. When an ink drop which has been transferred to a substrate passes over into a gel during the cooling process, the consequence is that the viscosity of the melted ink drop increases greatly so that the drops become relatively immobile. In this way the ink drops are prevented from uncontrollably flowing into the paper. As a result, inks of this kind are suitable for use on both porous and smooth substrates. In addition, these inks have been found suitable for use in a printing device in which printed substrates are subjected to thermal after-treatment.Type: GrantFiled: July 7, 2000Date of Patent: October 29, 2002Assignee: Oce Technologies B.V.Inventors: Erik Kelderman, Marcus Petrus Leonardus Huinck, Nicolina Margriet Kortenhoeven, Frederik Leonardus Everardus Marie Suilen, Guido Gerardus Willems, Albin Bernhard Werner Haas -
