Abstract: A silver composition is disclosed which contains silver powder or flake, a water soluble binder, an organic water soluble solvent and an inorganic binder. Generally, the composition will also contain water. The water soluble binder is especially chosen such that it has the property after dissolution in water, followed by water removal that it can be again dissolved in water (as opposed to water resistance as in a paint). The silver composition as a film or coating also lacks water resistance (prior to a firing operation) which can aid in pattern formation.

Abstract: The present invention is directed to a positive temperature coefficient composition comprising by weight based on total composition, 10-30% carbon black possessing a DBP absorption of about 125 cc/100 g carbon black or less; 10-40% chlorinated, maleic anhydride grafted, polypropylene resin; and organic medium capable of solubilizing the resin.
