AbstractAqueous ink formulation containing metal-based nanoparticles for usage in micro contact printingThe present invention relates to an aqueous formulation particularly for generating electrically conductive and/or reflective structures by microcontact printing, characterized in that the formulation contains at least>.15 to <55 parts by weight water,10 to parts by weight alcohol,>.15 to <45 parts by weight metal-based nanoparticles,d) >40,5 to <10 parts by weight non-fluorinated surfactant, ande) >.13,5 to <10 parts by weight fluorinated surfactant,wherein the above defined constituents a) to e) summarize to a concentration of 100 parts by weight in the formulation. The wetting behavior especially of hydrophobic materials may significantly be improved. The present invention further relates to a method of generatingstructures, particularly being electrically conductive and/or reflective, on a substrate by microcontact printing and a substrate comprising such a structure.
