Rewritable, heat sensitive, color image recording medium and image recording method using same |
摘要 |
A rewritable, heat sensitive, color image recording medium having a pair of opposed substrate sheets at least one of which is transparent, and a heat sensitive layer interposed between the substrate sheets and containing a cholesteric liquid crystal compound having a molecular weight of not greater than 2,000 and a glass transition point of at least 35° C. A color image is formed on the recording medium by varying imagewise the temperature of the heat sensitive layer from a first temperature to a second temperature such that the cholesteric liquid crystal compound assumes a cholesteric liquid crystal phase at at least one of the first and second temperatures. The image is fixed by rapidly cooling the recording medium to a temperature lower than the glass transition point of the cholesteric liquid crystal compound.
