<p>A conductive pattern forming compsn. contains, as major components, (a) an alloy powder, (b) a glass fit and (c) an organic vehicle. (a) is obtained by pulverising finely a cooled eutectic mixture of Ni (99.5-94.5 pref. 98.5-96.0 wt.%, best 98.0-96.3 wt.%) and B (0.5-55 wt.%, pref. 1.5-4.0 wt.%, best 2.0-3.7 wt.%). The particles of (a) are spherical, of dia 10 microns. The softening pt. of the glass frit, which lies between 400-500 deg.C, is higher than the decomposition temp. of the organic vehicle. The weight ratio of alloy powder to glass frit is 1-40. The conductive pattern is formed by kneading the mixture of (a), (b) and (c), making it into a paste, using a printing technique to print a pattern of the paste on the substrate, and then baking. The alloy powder can be obtd. by a water atomising method. The conductive pattern is also obtd. by making a toner by mixing the alloy powder coated with an insulating layer with the glass frit also coated with an insulating layer, transprinting the pattern on the substrate with the toner using a static electric technique, and baking. The conductive pattern can be produced on a plasma display substrate.</p> |
