Thermal recording process has been favorably applied to facsimile and non-impact printers of computer output, because of its advantages such as simplicity, cleanness and maintenance-free. However, for unstability of the formed image and possibility of additional printing, this process is unsuitable for print certificates and official documents. The thermal dye and/or ink-transfer printers possess same merits as thermal printers and are able to form the stable image.
We have developed the thermal ink-transfer printer for season ticket, and have tried to compat this printer. As one of improvement of this printer, uses of photofixable type thermal paper in place of ink-transfer tape have been investigated.
Several diazo type thermal papers were prepared using several kinds of diazonium salt and guanidine derivatives which are fusible base, and their print characteristics were examined.
Some of the thermal papers prepared are as sensitive as the commercial thermal paper, and is not inferior to the photo sensitive diazo type paper in the stability. It is able to estimate that photo-decomposition rate of diazonium salt in the layer coated on paper as well as in solution.
