ABSTRACT:
A ceramic color composition for coating a glass plate with the same includes first and second inorganic pigments, an optional filler, a low melting point glass frit, a resin and an oil. The total of the first and second inorganic pigments and an optional filler amounts to "A" parts by weight. The low melting point glass frit amounts to "B" parts by weight. The first and second inorganic pigments have average particle sizes ranging from 0.1 to 1.5 .mu.m and from 2 to 50 .mu.m, respectively. A ratio of "A" to the total of "A" and "B" ranges from 0.08 to 0.40. A ratio of the amount by weight of the first inorganic pigment to the total of "A" and "B" ranges from 0.05 to 0.25. A ratio of the amount by weight of the second inorganic pigment to the total of "A" and "B" ranges from 0.03 to 0.15. The ceramic color composition is substantially improved in releasability of the same from a bending press mold.
