Inkjet inks for ceramic tile decoration

A solvent-based pigmented ceramic inkjet ink composition comprising a solvent blend wherein the solvent blend comprises one or more hydrophobic solvent(s) and one or more water-soluble hydrophilic solvent(s);

• wherein:
• (i) the one or more hydrophobic solvent(s) are selected from the group consisting of C12-C30 aliphatic hydrocarbons, dioctyl cocoate and blends thereof and the one or more water-soluble hydrophilic solvent(s) comprises at least one glycol and/or glycol dialkyl ether, or glycerol;
• or
• (ii) the one or more hydrophobic solvent(s) is dioctyl cocoate and the one or more water-soluble hydrophilic solvent(s) comprises at least one glycol monoalkyl ether.

A solvent-based pigmented ceramic inkjet ink composition comprising a solvent blend wherein the solvent blend comprises one or more hydrophobic solvent(s) and one or more water-soluble hydrophilic solvent(s);

• wherein the one or more hydrophobic solvent(s) are selected from the group consisting of C12-C30 aliphatic hydrocarbons, high boiling point ester solvents (preferably esters having a boiling point of greater than about 235° C., preferably greater than 280° C.) and blends thereof;
• and
• wherein the one or more water-soluble hydrophilic solvent(s) comprises one or more glycol(s) and/or glycol ether(s), or poly(ethylene) glyol(s);
• wherein the one or more glycol(s) is selected from ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, tetrapropylene glycol, butylene glycol, dibutylene glycol, tributylene glycol or tetrabutylene glycol;
• and
• wherein the one or more glycol ether(s) is selected from dipropylene glycol monobutyl ether, dipropylene glycol monopropyl ether, propylene glycol monobutyl ether, propylene glycol monopropyl ether, tripropylene glycol monobutyl ether, dipropylene glycol monomethyl ether, dipropylene glycol dimethyl ether, ethylene glycol phenyl ether or propylene glycol methyl ether.
