Abstract

1334060 Electro-photographic material XEROX CORP 21 Dec 1970 [2 Jan 1970] 60557/70 Headings G2C and C17E An electro-photographic material is prepared by adding alpha, alpha and beta or alpha and X-form phthalocyanine and a binder to a liquid medium and "sand" milling the mixture until at least a portion of the alpha phthalocyanine is converted to beta phthalocyanine. By "sand" milling is meant milling with small beads including sand, glass beads and ceramic beads. In an embodiment alpha metal-free phthalocyanine, a silicone resin, a chlorinated resinous paraffin and an acrylic resin in toluene are milled in sand at 120-180‹F. for 0.2 to 2 hours. The milled composition is coated on a support of paper, plastics, Al or brass to form an electro-photographic element. Comparative examples are given wherein the milling medium is larger diameter steel balls or flint pebbles.
