ABSTRACT:
A composition utilized in and a method for forming an electrode used in field emission type of display devices said composition is a photosensitive copper conductive composition comprising: a mixture of (a) copper powder at least 70 wt % out of 100 wt % copper powders having a particle size in the range of 0.2-3 μm and (b) an inorganic binder with a softening point in the range of 380-580° C. in an amount of 140 wt % based on 100 wt % copper powders, said mixture being dispersed in an organic vehicle comprising (c) an organic polymer binder, (d) a phototoinitiator, (e) a photohardenable monomer, and an organic solvent; and the photosensitive copper conductive composition being fireable at a temperature in the range of 450-600° C. in a reductive atmosphere.
