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.
