ABSTRACT:
A silver-containing, disperse, water-containing formulation and its use to produce electrically conductive and/or optically reflective coatings is described. The formulation contains at leasta) 0.5 to 30 parts by wt. of silver metal particles with an effective diameter of at most 150 nm, preferably at most 100 nm, particularly preferably 40 to 80 nm, with a bimodal size distribution,b) 50 to 99.5 parts by wt. of water and optionally up to 30 parts by wt. of solvent,c) 0.01 to 10 parts by wt. of at least one, in particular polymeric, dispersant,d) 0 to 5 parts by wt. of film-producer,e) 0 to 5 parts by wt. of additives,f) 0 to 5 parts by wt. of conductive polymers,and has a viscosity of at most 150 mPa.s.
