Title: Thermosensitive recording medium
Inventor: MATOBA GENSUKE
IPC: B41M5/337
Filed: 1988-12-23
Abstract: PURPOSE:To allow stable recording without any harmful phenomena such as fog and blocking and free from any adverse change in external environments by adding at least synthetic hecrite clay and soap-free emulsion binder to a rear layer which forms a recording medium. CONSTITUTION:A thermosensitive recording medium consists of a recording layer which contains colorless or pale basic dye and coloring agent which allows said basic dye to develop color by heating on a transparent support. At least synthetic hecrite clay and soap-free emulsion binder are added to the rear layer which forms the recording medium. Consequently, data can be recorded constantly in a stable recording condition without any external environment conditions such as humidity or recording conditions such as recording speed. Therefore, it is possible to prevent generation of 'blocking', if the recording medium is stored in a condition where it is wound up.
