PROBLEM TO BE SOLVED: To form thin high aspect ratio features in a conductive structure. SOLUTION: The paste composition comprises (a) a source of electrically conductive metal, (b) 0.25 to 8% by weight of glass frit based on the total weight of the paste composition, and (c). ) An organic vehicle, wherein the source of electrically conductive metal and the glass frit are dispersed in the organic vehicle, the organic vehicle comprising an organic polymeric material and a solvent, the organic polymeric material comprising: Microgel particles having polymer units having a molecular weight in the range of 10 7 to 10 12 , and optionally one or more additional polymeric materials, the total amount of said organic polymeric material being the total weight of said paste composition. Based on 0.01 to 5% by weight, the paste composition. [Selection diagram] Figure 1F |
