20090297796 | Water-Based Screen Printing Ink - A water-based screen printing ink composition which can be used for flexo or gravure printing includes an acrylic or urethane-acrylic copolymer emulsion, a crosslinker, a pigment selected from the group consisting of luminescent pigments, magnetic pigments, optical effect pigments, optically variable pigments, and a catalyst. The crosslinker has at least two different chemical functionalities within the same molecule, a first of which forms a covalent link with the polymer prior to printing and a second of which effects crosslinking of the polymer to cure the printed ink. | 12-03-2009 |

20090184169 | Coating Composition for Producing Magnetically Induced Images - The present invention is related to a coating composition for the production of a magnetically induced image, consisting of volatile components (S) and non-volatile components, the latter consisting of an ink vehicle (I) and magnetically orientable optically variable interference pigment (P), to a process for manufacturing the coating composition, and to the use of the composition for the production of a magnetically induced image coating on a substrate with the help of applied magnetic fields. Said magnetically induced image coating may be used as a security device on value- or identity documents, brand protection labels and the like. | 07-23-2009 |
20110109076 | INTAGLIO PRINTING INK COMPRISING DENDRIMERS - An ink for the engraved copperplate intaglio printing Hyperbranched polyesters inks is disclosed, which comprises high-molecular-weight dendritic polymer as a binder component. Inks comprising such polymer can be formulated so as to contain a significantly reduced amount of organic solvent (volatile organic components, VOC) whilst still being in the appropriate viscosity range required by the intaglio printing process. The printed and cured intaglio ink of the present invention has improved chemical and mechanical resistance properties. | 05-12-2011 |
20110298207 | MAGNETICALLY ORIENTED INK ON PRIMER LAYER - Disclosed is a security document (D), having a substrate (S) coated with at least one first coating layer (P), and over said first coating layer (P) at least one second coating layer (I), said second coating layer (I) comprising at least one type of magnetic or magnetizable particles (F), wherein indicia are embodied in the coating layer (I) through a selective orientation of the said magnetic or magnetizable particles (F). Further disclosed is a process of making said security document. | 12-08-2011 |

20150072117 | PERMANENT STAINING OF VARNISHED SECURITY DOCUMENTS - The present invention relates to the field of the protection of security documents, especially banknotes, against illegal actions such as robbery or theft. In particular, the present invention relates to the field of ink-stained documents that are resistant to chemicals. The disclosed security documents are covered on at least one side by from about 70% to about 90% of a protective varnish and comprising from about 10% to about 30% of one or more varnish-free areas comprising one or more varnish-free indentations (I), the percents being based on the total surface of the one side of the security document. | 03-12-2015 |
