Resumen de: WO2026058177A1
The invention relates to a security substrate for security documents, which is formed based on a laminated structure comprising two BOPP films with appropriate thickness and structure so as to improve durability, enhance tactile feel, and provide advantages in circulation. The security substrate according to the present invention comprises a lower surface and an upper surface. The substrate comprises a laminated structure of two BOPP films bonded together by an adhesive layer. The thickness of the BOPP film layers provides the laminated structure with improved tensile strength compared to the prior art. The coating layers may be applied to one side of the laminated structure, and are preferably applied to both sides of the laminated structure, for example, two coating layers on each side. The thickness of the coating layer, in combination with the laminated structure, provides advantages in terms of tactile feel.

Activation indicia, such as a barcode, can be printed or otherwise applied to an exterior portion of the card assembly, or printed or otherwise applied to an interior of the assembly which is accessed by a tamper evident pull tab. Redemption indicia, such as an alpha-numeric code, can be applied to an interior surface of the card, which is accessed by a tamper evident pull tab or other tab.
Resumen de: WO2024231418A1
The present invention relates to compositions, comprising silver nanoplatelets, wherein the silver nanoplatelets are capped by a compound of formula (XX), wherein R41 is a C4-C25alkyl group, which may be interrupted by one, or more oxygen atoms, and n is a number 1 to 10, especially 1 to 4, very especially 1, or 2, a process for its production, printing inks containing the compositions and their use in security products. The capping with the compound of formula (XX) renders the surface on the nanoparticles more hydrophobic, while maintaining colloidal stability of their dispersions in organic solvents and/or monomer compositions. This combination of properties allows for production of stable UV curable coating/printing compositions, suitable for manufacture of dichroic security elements for protection of value documents. The surface modification, described in the present invention is suitable for silver nanoplatelets of different sizes and, correspondingly, colors, and is especially useful for manufacture of solvent-free coating, or printing compositions.
