Problems solved by technology

[0002] Today's world is in the era of informationization, and various high-tech industries have higher and higher requirements for information storage, and the storage technologies widely used at present are all surface storage technologies, such as magnetic storage or optical disk storage, and the storage density is close to the theoretical level. In addition, the two-dimensional information display method has become somewhat monotonous, and the display of image information is not comprehensive enough. The true three-dimensional and immersive information display method has become the focus of attention. Therefore, the research on the new storage technology of the whole series storage imperative

Abstract

A multi-component photoinitiation system and a photopolymer material, the multi-component photoinitiation system includes a photoinitiation accelerator of the structure shown in formula (1): wherein, X is O, S or N, and R is selected from H, halogen or nitro. Applying the multi-component photoinitiating system to the photopolymer material can significantly improve the performance of the photopolymer.

Description

technical field [0001] The invention relates to the technical field of photosensitive materials, in particular to a multi-component photoinitiating system and a photopolymer material. Background technique [0002] Today's world is in the era of informationization, and various high-tech industries have higher and higher requirements for information storage, and the storage technologies widely used at present are all surface storage technologies, such as magnetic storage or optical disk storage, and the storage density is close to the theoretical level. In addition, the two-dimensional information display method has become a little monotonous, and the image information display is not comprehensive enough. The true three-dimensional and immersive information display method has become the focus of attention. Therefore, the research on this new storage technology of the whole system It is imperative. As a class of holographic storage materials, photopolymers have the characteris...
