High Speed Photopolymer for High Density Black Matrix

Abstract

Photopolymer compositions for a high density black matrix, which was applied to a flat-bed display, have been investigated.

To obtain the higli density matrix, new epoxyacrylate monomers, which worked as a dispersing reagent of carbon black (CB) and as a polymerizing reagent, and high speed photo-initiator systems containing a new singlet-sensitizer dye were developed.

The relation of the image formation and the pigment dispersing character with the chemical structure of the monomers, and photo-initiating mechanisms, which wen analyzed by a laser flash photolysis in a polymer film, are discussed.
