Abstract
Flexible, electroluminescent panels or lamps employ a phosphor which is embedded in a coating formulation, in which a polyester laminating resin has been activated by a catalyst containing toluene diisocyanate or diphenylmethane diisocyanate, to provide a relatively high dielectric constant and to provide a flexible panel which is resistant to shorting, due to trimming, cutting or puncturing. The panel is characterized by relatively high efficiency and high light output.
