An improved electroluminescent lamp is described comprising a desiccant layer comprising a formed-in-place patternable hygroscopic film layer.

Electroluminescent lamp and method of manufacture

Disclosed is a thermally stable liquid negative developer comprising an organic liquid carrier, a pigment, a stabilizing gel on the borderline of solubility in the carrier, a latex which imparts a fixative function to the developer, and a two component charge control agent. The charge control agent consists of a first polymer, soluble in the carrier, having a basic character because of the inclusion of pyrrolidone or hydroxylated alkyl groups, and a second polymer, insoluble or on the borderline of solubility in the carrier, having an acid character because of the inclusion of free halogenated groups, and containing a minor amount of carrier soluble moieties. The two components may constitute separate ingredients, or either or both components may be incorporated into the structure of other developer components. Thus, the basic component may be included in the gel, and the acid component included in the latex. The image density of copies produced with the developer remains at optimum levels although the developer is subjected to elevated temperatures in storage or use.
