Individual inks and an ink set for use in generating intermediate colors via the combination of separate inks applied by an ink jet printer to the glazed surface of an article, such as glazed ceramic architectural tile for example, that is to be heated to a temperature of greater than 300° C. The ink set according to the present invention includes at least three separate inks that upon heating decompose to form colored oxides or colored combinations with the materials of the glazed surface upon which they are applied. A first ink of the ink set includes a soluble cobalt complex for use in forming a cyan color. A second ink of the ink set includes a soluble gold complex for use in forming a magenta color. And, a third ink of the ink set includes a soluble transition metal complex for use in forming a yellow color. The third ink preferably includes a soluble praseodymium complex. Alternatively, the third ink includes a blend of soluble chromium and antimony complexes and/or soluble nickel and antimony complexes. The ink set also preferably includes a fourth ink including a soluble ruthenium complex for use in forming a black color. The inks preferably contain no suspended solids and are preferably water immiscible. The invention also provides a method of decorating a glazed article using the inks of the ink set, and an article having a decoration applied to at least one glazed surface thereof.
An ink set for use in decorating the glazed surface of an article using an ink jet printer, the ink set comprising at least three separate inks containing soluble transition metal complexes that upon heating to a temperature of greater than about 300° C. decompose to form colored oxides and/or colored combinations with one or more materials of the glaze, a first ink of the ink set comprising a soluble cobalt complex for use in forming a cyan color, a second ink of the ink set comprising a soluble gold complex for use in forming a magenta color, and a third ink of the ink set comprising a soluble transition metal complex for use in forming a yellow color.
A method of decorating a glazed surface of an article with an ink jet printer comprising:
An article having a decoration applied to at least one glazed surface thereof, the decoration being formed using an ink jet printer and an ink set comprising at least three separate inks containing soluble transition metal complexes that upon heating to a temperature of greater than about 300° C. decompose to form colored oxides and/or colored combinations with one or more materials of the glaze, a first ink of the ink set comprising a soluble cobalt complex for use in forming a cyan color, a second ink of the ink set comprising a soluble gold complex for use in forming a magenta color, and a third ink of the ink set comprising a soluble transition metal complex for use in forming a yellow color.
An ink for use in forming a decoration on a glazed surface of an article that is to be heated to a temperature of greater than 300° C., said ink comprising a soluble cobalt complex and one or more solvents selected from the group consisting of aromatic hydrocarbons, unsaturated hydrocarbons, saturated hydrocarbons, fractions of petroleum distillates, cyclic saturated hydrocarbons, ethers, esters, alcohols, and nitriles, said ink being water immiscible.
An ink for use in forming a decoration on a glazed surface of an article that is to be heated to a temperature of greater than 300° C., said ink comprising a soluble praseodymium complex and one or more solvents selected from the group consisting of aromatic hydrocarbons, unsaturated hydrocarbons, saturated hydrocarbons, fractions of petroleum distillates, cyclic saturated hydrocarbons, ethers, esters, alcohols, and nitriles, said ink being water immiscible.
