Dispersion metallic pigment incorporation

When incorporating metallic pigments into plastics care needs to be taken as not to damage the flake during the dispersing process which would result in reduced brilliance. Since aluminum and bronze pigments disperse very easy, this represents no problem. 

The photoconductivity of organic dyes, especially phthalocyanine pigments, could be utilized to provide reusable or non-reusable electrophotographic plates having sensitivities that extend over the entire visible spectrum and produce high-contrast images 167,168) Microcrystalline dispersions of metal-free phthalocyanine in suitable binders have a white-light sensitivity equal to that of selenium 169> and can be incorporated into coated papers and drums.
