Abstract
An electroluminescent system in which neighboring layers are suspended, prior to application, in advantageously a unitary carrier compound, so that after curing, the layers form active strata within a monolithic mass. The carrier compound in a preferred embodiment is a vinyl resin in gel form. The invention enables several manufacturing advantages, including the ability to screen print the entire electroluminescent system on a variety of porous or fibrous substrates.
