    摘要： This invention provides 1,1-bis(4-hydroxyphenyl)-1-phenylethane having a crystal form characterized by an X-ray diffraction pattern having one sharp and strong peak 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 storing stability of a colored image and a non-colored portion against heat, water or the like and the low-energy color-developing property suitable for high-speed color development.

    摘要翻译： 本发明提供了具有以16.4°具有一个锐锐强峰的X射线衍射图的特征的结晶形式的1,1-双（4-羟基苯基）-1-苯基乙烷和在13°的每一个处具有三个中等强度的尖峰 -16°和17°-20.8°，并且在具有Cu-Kα射线的X射线衍射中，在22°-23°处具有至少三个中心强度的峰作为衍射角（2θ），并且能够给出 彩色图像和无色部分对热，水等的储存稳定性和适于高速显色的低能量显色性。
