Abstract:
1. A composition for printing conductor tracks onto a substrate using a laser printing process, the composition comprising: 30 to 90% by weight of electrically conductive particles having a particle size of 100 nm to 100 μm, 0 to 7% by weight of glass frit, 0 to 8% by weight of a matrix material, 0 to 8% by weight of an organometallic compound, 0 to 5% by weight of an additive, 3 to 69% by weight of a solvent, not more than 1% by weight of elemental carbon, and 0.5 to 15% by weight of nanoparticles as absorbents for laser radiation, the nanoparticles comprising silver, gold, platinum, palladium, tungsten, nickel, tin, bismuth, iron, indium tin oxide, titanium carbide, tungsten oxide or titanium nitride, wherein the nanoparticles are prism-shaped nanoparticles having an edge length of 15 to 1000 nm and a height of 3 to 100 nm.
