Patent ID: 8158032

Claim:
A conductive ink composition comprising organic-stabilized silver nanoparticles and a solvent, and a polyvinyl alcohol derivative resin of Formula (1) wherein R 1 is a chemical bond or a divalent hydrocarbon linkage having from about 1 to about 20 carbons; R 2 and R 3 are independently an alkyl, an aromatic or substituted aromatic group having from about 1 to about 20 carbon atoms; x, y and z represent the proportion of the corresponding repeat units respectively expressed as a weight percent, wherein each repeat unit is randomly distributed along polymer chain, wherein x is from about 5 to about 15, y is from about 80 to about 95 and z is from 0 to about 5, and the sum of x, y and z is about 100 weight percent, and wherein the polyvinyl alcohol derivative resin is present in an amount of from 0.1 to about 5 weight percent of the ink composition.
