COMPOSITIONS, COMPRISING SILVER NANOPLATELETS

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.
