Method of manufacturing thermosensitive recording medium

摘要

A thermosensitive recording medium 1 is produced by printing a first water-dispersion thermosensitive ink by a printing method that uses a printing plate on a substrate on a surface of which an ink receptive layer impregnating the first water-dispersion thermosensitive ink is provided, and then printing a second water-dispersion thermosensitive ink using the same printing method. The first water-dispersion thermosensitive ink is prepared by dispersing a pigment that contains at least an electron-donating compound in water, and the second water-dispersion thermosensitive ink contains one or both of at least an electron-accepting compound and a sensitizer that enhances thermosensitive sensitivity. This simplifies a process for manufacturing a thermosensitive recording medium using a printing plate and reduces the manufacturing costs.
