    摘要: 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.

    摘要: This invention is a quaternary ammonium/isocyanate compound having the formula OCN-Z-Q.sup.+ A.sup.-, wherein Z is a divalent organic moiety; Q is a quaternary ammonium moiety; and A is a monovalent anionic counterion. Use of this quaternary ammonium/isocyanate compound or its amine/isocyanate compound enables one to convert any hydroxy containing binder into a self-wetting binder.
