Two types of photochromic fulgide compounds [(1,2,4-trimethyl-5-phenyl)-3-pyrryl-ethylidene (isopropylidene) fulgide and (p-N,N-dimethylphenyl-2-methyl)-3-oxazoleyl-ethylidene (isopropylidene) fulgide] were used to prepare single layer bicolor PMMA composite film. The experiment demonstrated that two different images could be recorded on the bicolor composite film at the same area by using two different wavelengths (650 nm and 488 nm) respectively. When using the corresponding wavelength 650 nm or 488 nm to readout the two stored images on the film, each wavelength can obtain a high contrast ratio image and the two images with little crosstalk. This experiment confirmed that it was feasible to store and readout two images at the same area of the bicolor photochromic fulgide material.
