CHIP SUSPENSION IN INKS, PAINTS OR VARNISHES, PROCEDURE FOR OBTAINING AND USING THEM TO TRANSFER THE CHIPS TO COMPLEX SURFACES BY MEANS OF WRITING, PRINTING OR PAINTING DEVICES (Machine-translation by Google Translate, not legally binding)

Resumen de: ES3014635A1

Chip suspension in inks, paints, or varnishes, method for obtaining and using it to transfer the chips to complex surfaces using writing, printing, or painting devices. The present invention describes a chip suspension that can be applied directly to spatially and geometrically complex surfaces to provide these surfaces with said chips using writing, painting, or printing devices, and the method for obtaining it. Furthermore, the present invention relates to the use of the suspension for decoration, marking, anti-counterfeiting or anti-fraud, coding, as sensors, as actuators, and for the manufacture of electronic devices, and to the use of the suspension for determining the dimensions of the channels of a writing, painting, or printing device.

METHOD FOR PRODUCING A FLUORESCENCE PROPERTY IN A MATERIAL USING A LASER

Resumen de: EP4541601A1

Es wird ein Verfahren (100) zum Erzeugen einer zumindest teilweisen Fluoreszenzeigenschaft in einem Material (10) bereitgestellt. Das Verfahren (100) umfasst das Bereitstellen (110) des Materials (10), das Bereitstellen (120) eines Lasers (20), das Anordnen des Materials (130) in einem Strahlengang des Lasers (20), so dass der Laser (20) das Material selektiv abschnittsweise bestrahlen kann, und das zumindest abschnittsweises Bestrahlen (140) einer Oberfläche (11) des Materials (10) mit dem Laser (20). Das zumindest abschnittsweise Bestrahlen (140) der Oberfläche (11) des Materials (10) mit dem Laser (20) findet so lange statt, bis sich sichtbare Schmauchspuren (12) auf den bestrahlten Bereichen (13) der Oberfläche (11) des Materials (10) bilden, wodurch eine Fluoreszenzeigenschaft in den bestrahlten Bereichen (13) erzeugt wird.

METHODS FOR PRODUCING OVERT SECURITY FEATURES EXHIBITING ONE OR MORE INDICIA

Resumen de: US2025121405A1

The present invention relates to the field of methods for producing eye-catching overt security features exhibiting one or more indicia as anti-counterfeit means on value documents or articles as well as decorative purposes. In particular, the present invention provides methods for producing security features that can be easily, directly and unambiguously authenticated by the human without any external device or tool, wherein said security features comprised a cured ink and one or more cured indicia, said ink comprising cured cationically curable compounds or cured hybrid curable compounds and silver nanoplatelets.

LUMINESCENT PRINTING INK FOR SECURITY PRINTING, ITEM HAVING LUMINESCENT FEATURE, AND PRODUCTION METHOD

Resumen de: US2025122394A1

A luminescent printing ink for security printing includes a fluorescent substance and a phosphorescent substance which each luminesce in the visible spectral range when excited with non-visible excitation light. The printing ink contains one or more capsule luminescent pigment varieties, each of which has a core, a shell encapsulating the core and a luminescent substance present in the core. The fluorescent substance and the phosphorescent substance are each present as a luminescent substance in the core of one or more of the capsule luminescent pigment varieties so that the capsule luminescent pigments form fluorescent capsule luminescent pigments and/or phosphorescent capsule luminescent pigments. The luminescences of the fluorescent and the phosphorescent capsule luminescence pigments have the same light-fastness and the same chemical stability, and their luminescences visually produce a substantially matching colour impression.

Resumen de: MX2024015173A

A scratch-off coating is provided which includes a first layer of ink comprised of a water-based ink; and a second layer of ink comprised of an ultraviolet-cured ink layered over said first layer of ink, wherein upon application of a scratching force said first layer of ink and said second layer of ink are removable from a surface on which said first layer of ink and said second layer of ink are applied.

INFORMATION RECORDING BODY, PRINTED ARTICLE, AND READING DEVICE FOR INFORMATION RECORDING BODY

Resumen de: EP4534299A1

The present invention addresses the problem of providing: an information recording body which can be easily read and deciphered by a typical reading device and for which reproduction or the like is difficult; and a reading device or the like for said information recording body. This information recording body 1 comprises a substrate 2, a bright ink layer 5 formed from bright ink on one surface of the substrate 2, a colored ink layer 3 formed from colored ink, and a transparent ink layer 4 formed from transparent ink, wherein: the colored ink layer 3 forms a first pattern 100; the transparent ink layer 4 forms a second pattern 200; the entire areas of the first pattern 100 and the second pattern 200 are superimposed, in plan view, on the region where the bright ink layer 5 is formed; the second pattern 200 includes information that can be converted into a specific code; and at least part of the second pattern 200 is superimposed on the first pattern 100.
