Rewritable, color image recording medium and image recording method using same

摘要

A rewritable, color image recording medium composed of a pair of opposed substrates at least one of which is transparent, and an intermediate layer interposed between the substrates. The intermediate layer contains at least one cholesteric liquid crystal compound having a molecular weight of not greater than 2,000 and a glass transition point of at least 35 DEG C., and a photochromic compound. By irradiating the intermediate layer imagewise with the light through the transparent substrate, while maintaining the intermediate layer at such a temperature that the cholesteric liquid crystal compound assumes a cholesteric liquid crystal phase, an image is formed. The image may be fixed by rapidly cooling the recording medium to a temperature lower than the glass transition.
