Beschreibung
Zusammenfassung:	An aqueous inkjet printing fluid composition for use in an inkjet printer comprising a silicon-based material which contacts the aqueous printing fluid composition, comprising in a concentration sufficient to inhibit corrosion of the silicon-based material when contacted by the aqueous printing fluid composition a soluble metal ligand complex of Formula (I): wherein M represents a divalent or a trivalent metal; Z represents OH or CO2H; n represents an integer from 1-4; each Y may independently be chosen from the group consisting of halogen, cyano, carboalkoxy, alkyl, alkoxy, aryl, hetaryl, carboxy, hydroxy, sulfo and phospho, or any two of Y on adjacent carbons may be combined together to form a 5-7 atom carbo- or heterocyclic ring; and the number of ligands y is 2 or 3; with the proviso that at least one Y comprises a solubilizing group capable of imparting water solubility to the complex. The useful lifetime of microelectromechanical fluidic devices based on silicon fabrication is extended.
