  • Writable and printable colloidal gold solution
    Patent number: 7579074
    Abstract: The present invention relates to an aqueous colloidal gold solution, comprising (a) nano-particular gold particles, (b) a compound having a polar tertiary amino group conjugated via a hydrophobic aromatic residue with a weaker alkaline group, and (c) a stabilizer comprising a mercapto group (—SH) and an acidic group, in particular a sulfonic acid group (—SO3?). This gold solution uses an ecologically compatible medium and is suited in an especial manner or writing and for printing, also for inkjet printers, since it has a long-term storage life and generates an attractive metal-like gold sheen.
