Problems solved by technology

The main components of photopolymer recording materials include film formers, monomers, crosslinking agents, and photoinitiation systems. Because the photon energy of red light is much lower than that of blue light and green light, the photosensitivity of red-sensitive photopolymer materials is low. The low photosensitivity of sensitive photopolymer materials seriously reduces the information recording speed and increases the production cost
And the photosensitivity of existing photoinitiators is low, which limits the application of red-sensitive photopolymer materials

Abstract

The invention relates to a red sensitive photopolymer material, a preparation method and applications. The material includes a photosensitizer and a photoinitiator; the photosensitizer includes methylene blue, malachite green or azure I; and the structure of the photoinitiator is shown as the description, wherein a substituent R is phenyl or C1-C4 alkyl. The photoinitiator based material has goodquantum yield and saturated exposure, and shows excellent photoinitiation characteristics.

Description

technical field [0001] The present application relates to a polymer material, further relates to a red-sensitive photopolymer material, a preparation method of the photopolymer, and an application of the polymer material. Background technique [0002] As a new type of holographic material, photopolymer materials have the characteristics of high diffraction efficiency, high refractive index modulation, no need for wet processing, and strong environmental stability. Storage, true 3D holographic maps, LCD displays, high-end anti-counterfeiting trademarks and other fields. When the photopolymer material is exposed to two beams of laser interference light, the photoinitiation system absorbs photon energy, releases active free radicals, initiates monomer polymerization, and forms a three-dimensional holographic grating inside the material, thereby realizing information recording. The main components of photopolymer recording materials include film formers, monomers, crosslinking ...
