Appeal No. 1997-4107
Application No. 08/510,730
THE INVENTION
The invention is directed to a photo conductive imaging
member having a photo generating layer. This layer contains a
specific mixture of hydroxy gallium phthalocyanine and
tetrafluoro hydroxy gallium phthalocyanine. Each of five
specified types of tetrafluoro hydroxy gallium phthalocyanine
is characterized by x-ray powder diffraction traces having
major and minor peaks characterized by specific Bragg angles.
THE CLAIM
Claim 1 is illustrative of appellants' invention and is
reproduced below.
A photoconductive imaging member consisting essentially
of a supporting substrate, a photogenerating layer, and a
charge transport layer, and wherein said photogenerating layer
is comprised of a mixture of a hydroxygallium phthalocyanine
and a tetrafluoro hydroxygallium phthalocyanine selected from
the group consisting of Type I tetrafluoro hydroxygallium
phthalocyanine with an X-ray powder diffraction trace having a
major peak at Bragg angles of 6.5, and minor peaks at 15.6,
and 26.5 degrees 21, Type II tetrafluoro hydroxygallium
phthalocyanine with an X-ray powder diffraction trace having a
major peak at Bragg angles of 6.6, and minor peaks at 12.7,
15.4, 26.3, and 27.0 degrees 21, Type III tetrafluoro
hydroxygallium phthalocyanine with an X-ray powder diffraction
trace having a major peak at Bragg angles of 7.5, and minor
peaks at 9.1, 15.6, 16.5, 19.5, 21.8, 22.6, and 27.3 degrees
21, Type IV tetrafluoro hydroxygallium phthalocyanine with an
