Patent ID: 7608784

Claim:
A photosensitive, photo-patternable, conductive paste for electrode formation, comprising: conductive metal particles, a glass binder, a monomer, a photoinitiator, an organic polymer binder, an organic medium and carbon black, wherein the content of the carbon black is 0.01 to 0.5 wt % based on the total paste weight, wherein the monomer content is 3-10 wt % of the total paste weight and wherein the monomer compound comprises one or more polymerizable ethylene group(s) and a compound containing at least one addition-polymerizable ethylenically unsaturated group, and wherein the glass binder is 1-10% of the weight % of the total paste weight and is composed of: 55-85 wt % Bi 2 O 3 0-20 wt % SiO 2 0-5 wt % Al 2 O 3 2-20 wt % B 2 O 3 0-20 wt % ZnO 0-15 wt % one or more of oxides selected from BaO, CaO, and SrO 0-3 wt % one or more of oxides selected from Na 2 O, K 2 O, Cs 2 O and Li 2 O.
