Beschreibung
Zusammenfassung:	The present invention provides a Pb free Ag paste composition for a PDP address electrode comprising a) 60 to 90% by weight of an Ag powder; b) 1 to 10% by weight of a Pb free inorganic binder; c) 0.001 to 1% by weight of an inorganic thickener; and d) 5 to 38% by weight of an alkali-soluble, negative photoresist composition for fine conductive powder dispersion. The Pb free Ag paste composition according to the invention i) is environment-friendly by using a Pb free inorganic binder, ii) is suitable for the fabrication of fine electrodes by using the prior electrode formation processes, iii) can apply the formed pattern to low temperature sintering processes of not higher than 600° C., iv) does not use a surfactant and stabilizer and has excellent printing, leveling and sintering performances by using an inorganic thickener and conductive Ag powder, and v) enables sintering to be carried out at a sintering target temperature without binder burning off zone.
