Abstract: The present invention provides a UV-Vis radiation curable security ink for producing a security feature for securing value documents, wherein said security feature exhibits a blue color upon viewing in transmitted light and a metallic yellow color upon viewing in incident light. The UV-Vis radiation curable security ink comprises a cationically curable or a hybrid curable ink vehicle, and silver nanoplatelets bearing a surface stabilizing agent of general formula (I) wherein the residue RA is a C2-C4alkyl group substituted with a hydroxy group; the residue RB is selected from a C1-C4alkyl group, and a C2-C4alkyl group substituted with a hydroxy group; and Cat+ is an ammonium cation of general formula +NH2RCRD, wherein the residue RC is a C2-C4alkyl group substituted with a hydroxy group; and the residue RD is selected from a C1-C4alkyl group, and a C2-C4alkyl group substituted with a hydroxy group.

Abstract: The present invention provides a process for manufacturing a security feature for securing a value document, wherein said security feature exhibits a blue color upon viewing in transmitted light and a metallic yellow color upon viewing in Incident light. The manufacturing process comprises the following steps: a) printing a specific UV-Vis radiation curable ink on a transparent or partially transparent region of a substrate of a value document; b) heating the ink layer obtained at step a) at a temperature of about 55° C. to about 100° C. for at least one second so that the ink layer exhibits a metallic yellow color upon viewing in incident light; and c) UV-Vis curing the ink layer obtained at step b) to form the security feature. The manufacturing process according to the present invention enables the expedient production of security features exhibiting a blue color upon viewing in transmitted light and a metallic yellow color upon viewing in incident light and is particularly useful for industrial printing of value documents.

Abstract: The present invention relates to the technical field of security documents comprising a security feature, such as a windowed security thread, a security foil, a security patch, a hologram or an ink printed security feature, and a protective coating, and methods of manufacturing of said security documents. The security feature has a security feature thickness tf of at least about 5 μm (micrometers) and a security feature surface facing away from the substrate consisting of a first region adjacent to the edges of the security feature and a second region non-adjacent to the edges of the security feature. The protective coating covers the security feature surface facing away from the substrate, a first substrate surface adjacent to the edges of the security feature, and a second substrate surface, which is different from the substrate surface covered by the security feature and the first substrate surface. The protective coating covering the security feature surface facing away from the substrate and the first substrate surface is transparent, the protective coating covering the first region has a thickness tb1, the protective coating covering the second region has a thickness tb2, the protective coating covering the first substrate surface has a thickness tc, and the protective coating covering the second substrate surface has a thickness ta. The thickness tc is larger than the thickness tf, which is larger than the thickness ta; the thickness tb2 is larger than the thickness ta; and either the thickness tc is larger than the thickness tb1, which is larger than or equal to the thickness tb2; or the thickness tc is equal to the thickness tb1, which is larger than the thickness tb2. The variable protective coating thickness on the surface of the security document provides the inventive security document with an increased resistance against physical and chemical attacks from the environment, while maintaining the mechanical resistance properties required for such security documents.
