ABSTRACT:
A phthalocyanine pigment dispersion using a dispersing polymer having pendant quaternary ammonium salt groups to form a highly dispersed and stable millbase is described. The pigment dispersion is compatible with poly(vinylbutyral) resins and stable in ketone solvents. The pigment dispersion is particularly useful as a charge-generating or charge-transport material in an organic photoconductor construction.
