Hydroxy gallium phthalocyanine crystals, a method for the production of the crystals, photoleitfaehiges material, which contains the crystal and an electrophotographic photoreceptor, the material contains

摘要

the invention relates to a process for the production of hydroxygalliumphthalocyaninkristalle, crystals, a photoleitfu00e4higes materialthe crystals contains a elektrophotographischen photorezeptor with this material. the photorezeptor elektrophotographische has extraordinary properties.the crystals of the hydroxygalliumphthalocyanins have different beugungspeaks in (i) 7,5u00b0, 9,9u00b0, 12,5u00b0, 16,3u00b0, 18,6u00b0, 25,1u00b0 and 28,3u00b0; (ii) 7,7u00b0, 16,5u00b0, 25,1u00b0 and 26,6u00b0; (iii) 7,9u00b0, 16,5u00b0, 24,4th and 27,6u00b0; (iv) 7,0u00b0, 7,5u00b0, 10,5u00b0, 11,7u00b0, 12,7u00b0, 17,3u00b0, 18,1u00b0, 24,5u00b0, 26,2u00b0 and 27,1u00b0 and (v) 6,8u00b0, 12,8u00b0, 15,8u00b0 and 26,0u00b0 the bragg angle (2 + 0.2) in ru00f6ntgenstrahlbeugungsspektrum.the elektrophotographische photorezeptor has a photosensitive layer, which contains the photoleitfu00e4hige material of the crystal.
