Pyrryl fulgide is a new type of organic photochromic material which can be used in EDRAW (Erase Direct Read After Write) optical memory. The absorption spectra of the bistability of the pyrryl fulgide are measured. The maximum absorption of the colored state is centered at 635 nm,the peak absorption of the bleached state is at 385nm. With the thermal stable states, optical images are steadily recorded on the pyrryl fulgide/PMMA film. The contrast of the recorded images is high enough, so it can be easily read out directly by a usual camera. The images on the film have been kept for six months without any degeneration. The storage period is estimated to be as years in dark at room temperature.
