The holographic storage characteristic of a new kind of water-resisting photopolymer is studied; and studied it's photoperceptivity and application in many aspects. The photopolymer is composed of two
dyes which is sensitive to red and blue wavelength. This kind of photopolymer is water-resisting and its
post retreatment is simple. The volume shrinkage mass of this material is also small. We have used this
material to make gratings successfully; we settled the problem of spreading this photopolymer to soft film for storage.
