CROSSLINKABLE PHOSPHINEOXIDE COMPOUND AND ITS PHOTOPOLYMER COMPOSITE

摘要

The present invention relates to a crosslinkable phosphine oxide compound and a photopolymerizable composition using the same, and more particularly, a novel phosphine oxide compound which can be easily polymerized by a general initiator or heat, and a binder component in the novel phosphine oxide compound. A photopolymerizable composition comprising a sol-gel solution prepared from a siloxane precursor or a transparent polymer resin and an appropriate amount of a photoinitiator, and a photopolymer for a photopolymerizable film having a high refractive index difference with a low shrinkage rate during photocuring and having an excellent optical recording effect It is about. The photopolymer for the photopolymerizable film prepared by photocuring the photopolymerizable composition of the present invention is not only very useful as a photopolymer for holographic data storage devices, but also exhibits excellent heat resistance, chemical resistance, mechanical rigidity and thin film properties to other color filters, Applications are expected in display component devices such as diffusion plate coating materials.;Phosphine Oxide Compounds, Photopolymerizable Compositions
