HIGH-SPEED PHOTOPOLYMER FOR HIGH-DENSITY BLACK MATRIX

Photopolymer compositions for a high density black matrix, which was a pplied to a flat-bed display, have been investigated. To obtain the hi gh density matrix, new epoxyacrylate monomers, which worked as a dispe rsing reagent of carbon black (CB) and as a polymerizing reagent, and hgh speed photo-initiator systems containing a new singlet-sensitizer dye were developed. The relation of the image formation and the pigmen t dispersing character with the chemical structure of the monomers, an d photo-initiating mechanisms, which were analyzed by a laser flash ph otolysis in a polymer film, are discussed.
