Problems solved by technology

[0007] However, although existing photopolymers can eliminate the wet processing process in the holographic recording medium process, the existing photopolymerization initiators have low sensitivity to light and cannot increase the recording speed of the holographic recording medium.

Abstract

The invention relates to a holographic recording medium and a composition for recording material thereof. The holographic recording medium comprises a base plate, a reflecting layer, a recording layer and a protection layer. The reflecting layer is arranged on the base plate. The recording layer is arranged on the reflecting layer and comprises a resin, a photopolymer and an initiator; the initiator comprises a photochromic material. The protection layer is arranged on the recording layer. The invention also discloses a composition for the recording material of the holographic recording medium. The monomer of the photopolymer is polymerized by virtue of the photochromic material of the invention, so that the wet processing in holographic recording medium manufacture is avoided.

Description

technical field [0001] The present invention relates to an optical recording medium and its composition for recording materials, in particular to a holographic recording medium and its composition for recording materials. Background technique [0002] Ideal holographic recording materials usually have the characteristics of wide spectral range, high resolution, high sensitivity, low signal-to-noise ratio and high diffraction efficiency. The existing holographic recording materials are imaged on the photosensitive film (mostly made of silver halide) by laser holographic interference light. After exposure, they need to go through a complicated wet processing process, and in the complicated wet processing process, due to the process The difference causes poor diffraction, and some materials will cause the hologram to blur and disappear due to the lack of strict maintenance of temperature and humidity. [0003] In order to solve this problem, the composition for the recording m...
