Color conversion films produced by UV curing processes

A color conversion film for a LCD (liquid crystal display) having RGB (red, green, blue) filters, the color conversion film prepared by UV (ultraviolet) curing from a formulation comprising:

• 5% photointiator, and
• 0.005-0.05% at least one rhodamine-based fluorescent (RBF) compound configured to absorb illumination from a LCD backlight source and have at least one of a R emission peak and a G emission peak;
