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 least n a) 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, n b) 50 to 99.5 parts by wt. of water and optionally up to 30 parts by wt. of solvent, n c) 0.01 to 10 parts by wt. of at least one, in particular polymeric, dispersant, n d) 0 to 5 parts by wt. of film-producer, n e) 0 to 5 parts by wt. of additives, n f) 0 to 5 parts by wt. of conductive polymers, n and has a viscosity of at most 150 mPa.s. |
