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, whose inherent thixotropic properties lend themselves to pre-suspending ingredients in the unitary carrier. The suspended ingredients may then be provided in kit form, ideally in the correct volumetric proportions. The invention enables several manufacturing advantages, including the ability to screen print the entire electroluminescent system on a variety of substrates, including cloth, metals, plastics, wood or even stone.
