Abstract
Solvent-based pigmented ceramic inkjet ink compositions including a solvent blend consisting predominantly of one or more hydrophobic solvent(s) (preferably one or more hydrophobic long chain hydrocarbon solvent(s)) are capable of achieving superior print quality when applied over unfired glazes by the inclusion of less than 10% by weight of the composition of a water-soluble solvent, especially glycol ethers. These ink compositions are particularly suited to ceramic tile decoration via the double fast firing process, with resulting improvements in absorption, color strength and print definition.
