    • A process for preparing an oxytitanium phthalocyanine hydrate crystal which, when dried at 100.degree. C. and 0.1 mmHg for 8 hours and then allowed to stand in air at room temperature for 12 hours, has a structural formula of TiOPc.multidot.(H.sub.2 O).sub.n, wherein Pc represents a phthalocyanine nucleus, and n represents a number of from 0.15 to 1, and elemental analysis values of C: 65.0 to 66.3%, H: 2.5 to 3.1%, and N: 18.5 to 19.3% is disclosed, which process comprises the steps of: mechanically grinding a mixture of oxytitanium phthalocyanine and an inorganic salt to convert the crystal form of the oxytitanium phthalocyanine to a crystal form showing a distinct peak in its X-ray diffraction pattern at a Bragg angle (2.theta..+-.0.2.degree. ) of 27.3.degree. and treating the resulting oxytitanium phthalocyanine crystal with a mixed solvent of water and a water-insoluble organic solvent. The oxytitanium phthalocyanine hydrate crystal obtained has doped therein a specific amount of water of crystallization and is stable in a solvent and also stable when used as an electrophotographic photoreceptor.
    • 一种制备氧钛酞菁水合物晶体的方法,其在100℃和0.1mmHg下干燥8小时,然后在室温下放置12小时,其结构式为TiOPcx(H 2 O)n,其中 Pc表示酞菁核,n表示0.15〜1的数,C:65.0〜66.3%,H:2.5〜3.1%,N:18.5〜19.3%的元素分析值, 步骤:机械研磨氧钛酞菁和无机盐的混合物,以将氧钛酞菁的晶体形式转变为在其布拉格角(2θ+/- 0.2°)的X射线衍射图中显示出不同峰的晶体形式 )为27.3℃,用水和水不溶性有机溶剂的混合溶剂处理得到的氧钛酞菁结晶。 获得的氧钛酞菁水合物晶体在其中掺入特定量的结晶水,并且在溶剂中是稳定的,并且当用作电子照相感光体时也是稳定的。
