摘要：This invention provides 1,1-bis(4-hydroxyphenyl)-1-phenylethane having acrystal form characterized by an X-ray diffraction pattern having one sharp and strongpeak at 16.4° and three sharp peaks of intermediate intensity at each of 13°-16° and 17°-20.8° and at least three peaks of intermediate intensity at 22°-23° as a diffraction angle(2θ) in an X-ray diffractometry with Cu-K α-rays, and being capable of giving the storingstability of a colored image and a non-colored portion against heat, water or the like andthe low-energy color-developing property suitable for high-speed color development.
