Abstract

PURPOSE:To prepare a recording medium suitable for a heat-sensitive recording paper for use with a facsimile and the like in which a particular indan compound is used as a developer, and which colors into a dark color, has a better preservation stability of a developed color, has a better preservation stability of a developed color picture and less sublimation of a develop. CONSTITUTION:(A) 1-95pts.wt. indan compound [example: 1,3,3-trimethyle- 1-(4-hydroxyphenyl)indan-6-ol and the like] which is represented by a formula [where R1, R2 are H, halogen, (cyclo)alkyl group of C1-4] is uses as a developer, and (B) 1-15pts.wt. an electron donative color former (example: crystal violet lacton and the like) are separately mixed in a medium, such as water, which does not dissolve them, togetherwith 1-40 parts a binder (example: PVA and the like) to prepare dispersion liquids which are applied on a supporting product, such as papers, for drying to produce a heat-sensitive recording sheet. EFFECT:To prepare a recording paper which has less ground-contamination and natural coloring. USE:To prepare a recording medium which can be effectively used with a developing sheet for a pressure-sensitive recording paper.
