Abstract

A photopolymer for fabrication of volume-type transmission holograms, which are used primarily on the holographic reflector for reflective LCD's, is reported. This photopolymer consists of bisphenol-type epoxy resin and an acrylic monomer with diaryliodonium salt and 3-ketocoumarin as a complex initiator. The chemistry of the imaging formation is based on the radical polymerization of the monomer initiated by a holographic exposure, followed by the cationic polymerization of epoxy resin by UV exposure after postexposure baking. The yellowish color of the hologram derivatives that resulted from the sensitizing dye and from the photospeed were improved to satisfy the specifications for the holographic reflector. The holographic reflector now gives brighter images.

摘要

报道了一种用于制造体全息透射光栅的光聚合物，该光栅主要用于反射型液晶显示器的全息反射器。这种光聚合物由双酚型环氧树脂和丙烯酸单体组成，以二芳基碘鎓盐和3-酮香豆素作为复合引发剂。成像形成的化学过程基于全息曝光引发的单体自由基聚合，然后在曝光后烘焙后通过紫外线曝光引发环氧树脂的阳离子聚合。由敏化染料和感光度导致的全息图衍生物的淡黄色得到改善，以满足全息反射器的规格要求。现在，全息反射器能提供更明亮的图像。
