The thermal recording device 7 is a device capable of converting electrical information into thermal information, and is preferably a thermal facsimile, a thermal printer, or the like. When the non-color developing area is left under room light, irradiated with visible or ultraviolet light, or heated, the diazonium salt in the non-color developing area is decomposed to provide a fixed thermosensitive recording paper.
以上述べたように、本発明による記録方法によ
れば、従来の感熱記録紙よりも安価に入手できる
乾式ジアゾ感光紙上に簡単な操作でしかも高速度
に画像転写でき、さらに非発色部が不所望の熱等
により再発色しない定着された画像をうることが
できるという顕著な利点がある。 As described above, according to the recording method of the present invention, it is possible to transfer an image onto dry diazo photosensitive paper, which is available at a lower cost than conventional thermal recording paper, with a simple operation and at high speed. It has the remarkable advantage that it is possible to obtain a fixed image that does not recolor due to heat or the like.
