An electroluminescent panel includes a release layer, a first insulating layer on the release layer, a plurality of lamp layers on the first insulating layer, and a second insulating layer overlying the lamp layers. In accordance with one aspect of the invention, the first insulating layer and the second insulating layer include low molecular weight PVDF/HFP resin. In accordance with another aspect of the invention, at least one of the lamp layers includes a UV-cured resin and the remaining lamp layers include a heat-cured resin.

Dimensionally stable electroluminescent lamp without substrate

EL panels are made with PVDF/HFP copolymer resin binder, in substantially an uncrosslinked form, with DMAC solvent and/or other higher boiling point solvents/latent solvents/extenders. The resin binder is characterized by a melt viscosity of 1.0-8.5 kP using an industry standard test (ASTM D3835).
