TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The glass frit further includes at least one element of lead, lithium, zinc, tungsten, phosphorus, silicon, magnesium, cesium, strontium, molybdenum, titanium, tin, indium, vanadium, barium, nickel, copper, sodium, potassium, antimony, germanium, gallium, calcium, arsenic, cobalt, zirconium, manganese, aluminum or boron. The glass frit includes 5-50 mol.% of lead. The glass frit is prepared from a mixture of metal oxides including 5-30 wt.% of bismuth oxide, 40-80 wt.% of tellurium oxide, 1-15 wt.% of chromium oxide, and 1-50 wt.% of a fourth metal oxide. The fourth metal oxides include at least one metal oxides of lead, lithium, zinc, tungsten, phosphorus, silicon, magnesium, cesium, strontium, molybdenum, titanium, tin, indium, vanadium, barium, nickel, copper, sodium, potassium, antimony, germanium, gallium, calcium, arsenic, cobalt, zirconium, manganese, aluminum or boron. The fourth metal oxide includes 1-10 wt.% of lithium oxide, 1-10 wt.% of zinc oxide, 1-10 wt.% of tungsten oxide and 15-50 wt.% of lead oxide, based on to total weight of the mixture of metal oxides. The content of silver powder, glass frit and organic vehicle is 60-95 wt.%, 0.5-20 wt.% and 1-30 wt.%, respectively. The glass frit has an average particle diameter (D50) of 0.1-10 mu m.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The composition further comprises at least one additive comprising a dispersant, a thixotropic agent, a plasticizer, a viscosity stabilizer, an antifoaming agent, a pigment, a UV stabilizer, an antioxidant or a coupling agent. The composition has a viscosity of 100000-500000 cps.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The organic vehicle includes a binder resin having a weight average molecular weight of 30000-200000 g/mol. EXAMPLE - 9 wt.% Bismuth trioxide, 76 wt.% tellurium dioxide and 1 wt.% of chromium trioxide were mixed together with 6 wt.% of lithium dioxide, 7 wt.% of zinc oxide and 1 wt.% of tungsten trioxide and subjected to melting and sintering at 900-1400 degrees C to prepare a glass frit having an average particle diameter of 2 mu m. 0.8 wt.% Ethylcellulose was dissolved in 8.5 wt.% Butyl carbitol (RTM: Diethylene glycol butyl ether) at 60 degrees C to prepare binder solution. 86.5 wt.% Spherical silver powder with average particle diameter of 2 mu m, 3.5 wt.% of the prepared glass frit, 0.2 wt.% of Byk102 (RTM: Dispersant) and 0.5 wt.% Thixatrol ST (RTM: Organically modified castor oil derivative) were added to the binder solution, followed by mixing and kneading in 3-roll kneader to prepare the composition.
