Claims7
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 %
- Bi2O3
- 0-20 wt %
- SiO2
- 0-5 wt %
- Al2O3
- 2-20 wt %
