ABSTRACT:
A colorless, heat-sensitive and heat transfer recording sheet with pressure sensitivity comprising a base sheet, a heat-sensitive recording layer provided on one side of the base sheet and a heat transfer recording layer provided on the other side of the base sheet, the heat transfer recording layer being formed by coating on the base sheet a coating color comprising 3 to 20 parts by weight of microcapsules containing a colorless, electron-donating color former, 3 to 30 parts by weight of microcapsules containing a colorless, electron-accepting color developer, 3 to 30 parts by weight of a solid of a colorless, electron-donating, color former, 10 to 50 parts by weight of a solid of a colorless, electron-accepting, color developer and 25 to 200 parts by weight of a wax.
When this recording sheet is superimposed on a plain paper and thermal printing is made on the recording sheet, there can be formed an image on the heat-sensitive recording layer of the recording sheet and, at the same time, a clear, heat transferred image on the plain paper. When the same combination of the above recording sheet and the above plain paper is subjected to pressure printing on the recording sheet, there can be formed a pressure transferred image on the plain paper.
