Claim:
A ceramic color composition comprising, as a solid power, 50 to 90 wt. % of a mixture containing 5 to 95 parts by weight of a first lead-free glass powder comprising at least SiO 2 , ZnO and B 2 O 3 as glass components, and 5 to 95 parts by weight of a second lead-free glass powder comprising at least SiO 2 , Bi 2 O 3 and B 2 O 3 as glass components, 10 to 40 wt. % of an inorganic pigment, and 0 to 10 wt. % of an inorganic filler, wherein the first glass powder and the second glass powder have the ratio of the components as described below: Ratio of the components of the first glass powder (wt.%) SiO 2 35-50 B 2 O 3 1-9 ZnO 15-40 TiO 2 0.5-10 Li 2 O 0.1-10 Na 2 O 0.1-10 F 0-5 K 2 O 0-10 ZrO 2 0-5 V 2 O 5 0-5 Ratio of the components of the second glass powder (wt.%) SiO 2 15-40 B 2 O 3 1-12 Bi 2 O 3 40-70 TiO 2 1-10 Li 2 O 0.1-10 Na 2 O 0.1-10 K 2 O 0-10 ZrO 2 0-5 V 2 O 5 0-5 F 0-5.
