Abstract:
Iodogallium phthalocyanine having a crystal form selected from those characterized by X-ray diffraction patterns (a)-(e) shown below respectively obtained by a CuK&agr; characteristic X-ray diffraction method:(a) having a strongest peak at a Bragg angle (2&thgr;Â±0.2 deg.) of 9.6 deg. and free from another peak having an intensity of 30% or more of that of the strongest peak, (b) having a strongest peak and a second strongest peak at Bragg angles (2&thgr;Â±0.2 deg.) of 9.4 deg. and 27.1 deg. wherein the second strongest peak has an intensity of at least 30% of that of the strongest peak, (c) having a strongest peak and a second strongest peak at Bragg angles (2&thgr;Â±0.2 deg.) of 7.5 deg. and 27.7 deg. (d) having a strongest peak and a second strongest peak at Bragg angles (2&thgr;Â±0.2 deg.) of 7.5 deg. and 26.4 deg., and (e) having (e)(i) a strongest peak, a second strongest peak and a third strongest peak at Bragg angles (2&thgr;Â±0.2 deg.) of 9.6 deg., 8.8 deg. and 27.2 deg., respectively, or (e)(ii) a strongest peak and a second strongest peak at Bragg angles (2&thgr;Â±0.2 deg.) of 27.2 and 8.8 deg., respectively.
