Abstract
A filament lamp for an emission of yellow light, with a color film which is formed on the surface of the bulb, where the color film is essentially composed of a combined oxide of titanium, nickel and antimony. The color film may have a ratio of titanium, nickel and antimony to one another in a weight ratio of 5.6 to 8.6:3.6 to 6.6:1.0 to 1.8. Also, the color film may be a sintered coating formed by admixing a solution A produced by dissolving a nickel salt and an antimony salt in an organic solvent, addition of a titanium alkoxide and reaction of the reaction mixture; and addition of a stabilizer which forms a chelate with titanium with a solution B produced in substantially the same manner as solution A. The solutions A and B contain nickel nitrate-6-hydrate, antimony trioxide, tetraisopropoxy titanium, acetyl acetone, and/or water.
