PURPOSE:To provide the thermal photographic printing method capable of photographic printing by using a recording medium which is recordable and erasable an unlimited number of times. CONSTITUTION:The recording medium 1 has a white layer 11 formed by coating a sheet type base material 10 such as paper and a plastic film with white paint and further has a recording layer 12 formed thereupon. In the recording layer 12, many microcapsules 4 containing liquid crystal 3 are dispersed in a binder 5 of acrylic resin, etc., and the microcapsules 4 are obtained by dispersing cholesteric liquid crystal among particulates and suspending them in a polymer solution such as PET. |
