A process for manufacturing a color-developing sheet from a combination of an electron-donating colorless dye such as no-carbon pressure-sensitive recording material, heat-developable image-recording material using heat-sublimable colorless dye, heat-sensitive, color-transferring image-recording material, etc. and an electron-accepting color-developing agent which comprises preparing a coating solution containing at least an inorganic color-developing agent, calcium carbonate, and a bisphenol compound. This coating solution has a low viscosity and a good fluidity at high solids, concentration in spite of the use of inorganic color-developing agent which usually causes troubles such as gelation. Thus, it facilitates coating work and provides good color-developing power of tile color-developing sheet, thus being excellent in printing properties. |
