Filament lamp for emission of yellow light

Filament lamp for an emission of yellow light which comprises:

• a glass bulb;
• a filament which is located in the bulb;
• and
• a color film which is formed on a surface of the bulb;
• wherein the color film is essentially composed of a combined oxide of titanium, nickel and antimony;
• wherein the color film is a sintered coating obtained by admixture of 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;
• and a solution B produced in the same manner as solution A, but with water added before the addition of the titanium alkoxide;
• wherein the solutions A and B contain nickel nitrate-6-hydrate in an amount of 7 to 13 weight percent, antimony trioxide in an amount of 0.6 to 1.2 weight percent, tetraisopropoxy titanium in an amount of 10 to 15 weight percent and acetyl acetone in an amount of 7 to 12 weight percent;
• and wherein solution B additionally contains water in an amount of 0.3 to 1.5 weight percent.
