Claims10
In a composition for printing electronic functions on a substrate comprising finely divided inorganic powders dispersed in a vehicle containing a volatile organic liquid and polymer viscosifiers, the improvement comprising, as the volatile organic liquid, a mixture of 5-80% by weight of said liquid of diethylene glycol dibutyl ether, and the remainder being a second more volatile organic liquid having a boiling point at least about 10.degree. C. less than that of said ether diethylene glycol dibutyl ether.
