Abstract: Inkjet compositions that can be applied to glass and/or ceramic substrates to impart contrast gloss (luster). The inkjet compositions include solvents, additives for dispersion, and inorganic substances, but preferably do not include any color-producing ceramic pigments. The inorganic substances contained in the inkjet compositions are responsible for the effects on the surface of the substrate.

Abstract: Inkjet compositions that can be applied to glass and/or ceramic substrates to impart various effect to the substrate after firing, including: gloss, matt, contrast gloss (luster), specular reflection (metallic appearance), relief and slipperiness. The inkjet compositions include solvents, additives for dispersion, and inorganic substances, but preferably do not include any color-producing ceramic pigments. The inorganic substances contained in the inkjet compositions are the responsible for the above mentioned effects on the surface of the ceramic article. Depending on the type of effect desired, the inorganic substance may be a specific frit, a crystalline oxide, or a combination of frits and crystalline oxides.
