This paper reports the synthesis of a negative photoresist, polypropanediol-(1, 3)-2-furylacroleinlidenemalonate (PPFM) and the change of photosensitization of PPFM to visible light when dye is appled. Experiments demonstrate that after photosensitivity is enhanced by methylenc blue and Wright’ s stain, PPF Mean be used aa relief phase holographic recording medium with He-Ne laser light.
