Nickel Compound-Containing Solution, Method of Producing the Same, and Method of Forming Nickel Metal Thin Film Using the Same

摘要

The present invention provides a nickel compound-containing solution having suitability for screen printing, and a method of forming a nickel metal thin film comprising applying the nickel compound-containing solution by screen printing. In a nickel compound obtained by reacting a reducing compound with nickel salt of organic acid, a nickel compound-containing solution, in which a nickel compound is stable and dissolved in terpineol, can be provided by using the specific structure compound as the reducing compound. This solution or the solution further containing resin such as cellulose and the like has the viscosity suitable for screening printing. A nickel metal thin film can be formed by applying the nickel compound-containing solution onto a substrate with screen printing and then heat-treating.
