摘要： A disperse formulation which contains silver and water, and its use for production of electrically conductive and/or optically reflective coatings, are described. The formulation comprises at least a) 0.5 to 30 % by weight of silver metal particles with an effective maximum diameter of 150 nanometres, preferably at most 100 nanometres, and particularly preferably 40 to 80 nanometres, with a bimodal size distribution, b) 50 to 99.5% by weight of water and, possibly, solvent amounting to up to 30% by weight, c) 0.01 to 10% by weight of at least one, in particular polymer, dispersant aid, d) 0 to 5% by weight of film former, e) 5 to 5% by weight of additives, f) 0 to 5% by weight of conductive polymers, and has a maximum viscosity of 150 mPa »s.
