Photopolymerizable photosensitive phosphor paste composition and method for forming fluorescent film of the same in PDP

Abstract

Photopolymerizable photosensitive phosphor paste composition useful for formation of a fluorescent film in a plasma display panel which is one of flat panel displays, and a method for forming a fluorescent film of the same in a plasma display panel. The photopolymerizable photosensitive fluorescent paste composition includes cellulose group water soluble binder polymer 100 wt.part, multifunctional monomer or oligomer 100 wt.part, photoinitiator 20 wt.part, fluorescent material 300 wt.part, a solvent for dissolving the cellulose binder polymer 150˜550 wt.part, and photoreaction rate controller 0.1˜5 wt.part. Accordingly, different from the related art photosensitive fluorescent paste, as the photopolymerizable photosensitive fluorescent paste of the present invention can be developed by pure water, the paste is environment friendly and has a low baking temperature, that permits an easy fluorescent film formation, the present invention is suitable for formation of a fluorescent film for a large sized screen over 40″ and an HDTV PDP.
