ABSTRACT:
An improved color-converting photoluminescent film that provides visible light emission in the red to green portion of the visible spectrum when excited by blue light. The color-converted photoluminescent film of the invention is patternable and has improved luminous efficiency and stability and is suitable for use in electroluminescent displays. The film comprises a mixture of a clear UV curable resin and photo-initiator which does not absorb blue light; and fluorescent pigment particles, wherein a molecular additive is optionally provided in to either or both of the pigment particles and curable resin. The mixture is screen printed onto a substrate to form a film and UV cured.
