ABSTRACT:
An opaque matrix that defines transparent apertures may be formed on a lenticular lens by applying an infrared radiation sensitive material to the flat surface of the lenticular lens, projecting infrared radiation through the lenticular lens onto the infrared radiation sensitive material to create exposed and unexposed areas of the infrared radiation sensitive material, and removing the exposed areas of the infrared radiation sensitive material from the flat surface of the lenticular lens. The infrared radiation sensitive material includes an infrared absorbing dye and a colorant. The infrared radiation sensitive material may also include a binder. A barrier layer may be disposed between the flat surface of the lenticular lens and the infrared radiation sensitive material. The barrier layer may include a binder, an infrared absorbing dye, and a crosslinking agent. The resulting lenticular lens may be used in a rear projection television screen or monitor.
