PCT No. PCT/US84/00922 Sec. 371 Date Nov. 16, 1984 Sec. 102(e) Date Nov. 16, 1984 PCT Filed Jun. 18, 1984 PCT Pub. No. WO85/00440 PCT Pub. Date Jan. 31, 1985.An hydroxyaluminumphthalocyanine colorant compound with reduced green absorption having peak absorption bathochromically shifted to 621 nm is disclosed. In a preferred embodiment, hydroxyaluminumphthalocyanine of the invention exhibits reduced absorption on both sides of the 621-nm peak as determined by the peak width at half maximum intensity. Hydroxyaluminumphthalocyanine is useful as an electrically photosensitive component in photoelectrophoretic imaging processes, as well as in electrographic developers as a toner constituent.
