| 摘要 |
The 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 a) ≧15 to ≦̸55 parts by weight water, b) ≧10 to ≦̸50 parts by weight alcohol, c) ≧15 to ≦̸45 parts by weight metal-based nanoparticles, d) 0.5 to ≦̸10 parts by weight non-fluorinated surfactant, and e) ≧0.5 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 generating structures, particularly being electrically conductive and/or reflective, on a substrate by microcontact printing and a substrate comprising such a structure. |
