Enhanced photoconductive oxo-titanyl phthalocyanine

摘要

Titanium dioxide added to oxo-titanyl phthalocyanine in a resin binder forming a charge generation layer having significantly improved dark decay and sensitivity. Added sensitivity is obtained when the X-form is precipitated from a dichloromethane/trifluoroacetic acid/oxo-titanyl phthalocyanine mixture by adding a water/methanol mixture containing titanium dioxide.
