Patent ID: 7824580

Claim:
A silver-containing, disperse, water-containing formulation containing at least a) 0.5 to 30 parts by wt. of silver metal particles with an effective diameter of at most 150 nm, with a bimodal size distribution of the silver metal particles, determined using laser correlation spectroscopy, 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 polymeric dispersant, d) 0 to 5 parts by wt. of film-producer, e) 0 to 5 parts by wt. of additives, f) conductive polymers, in an amount of up to 5 parts by wt., said formulation having a viscosity of at most 150 mPa.s.
