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.
