Abstract
PURPOSE:To provide the above-described material, which gives clear images with high contract, by adding cycloheptaamylose to a water-dispersion solution of leuco- dye when it is adjusted, and thereby preventing fogging and increasing surface white color. CONSTITUTION:In adjusting a water-dispersion solution consisting mainly of a colorless or light-color leuco-dye, this is added with cycloheptaamylose, preferably 1-10 weight parts (with respect to 1 weight part of leuco-dye). A water-dispersion solution mainly consisting of the resultant water-dispersion solution, an acidic substance, and/or a phenol compound, is coated on a supporting body and is dried. Thus, the desired material is obtained.
