Abstract

1311598 Electro-photography FUJI PHOTO FILM CO Ltd 17 Sept 1971 [18 Sept 1970] 43562/71 Heading G2H A liquid developer comprises an insulative carrier liquid and suspended pigment containing adsorbed resin soluble in the carrier liquid, the weight ratio of resin to pigment being more than 0. 5. A toner concentrate containing less than 20 per cent of solid and having a viscosity of less than 20 centipoises may be prepared by ball milling resin, pigment and carrier liquid; and developer formed therefrom by dilution with further carrier liquid. The pigment may be carbon black and the resin an alkyd resin.
