Abstract

1309353 Electro-photographic developers MITA INDUSTRIAL CO Ltd 19 April 1971 [20 Feb 1970] 22206/71 Heading G2H Liquid electro-photographic developer comprises a dispersion of (a) negatively charged particles of at least one dyestuff, pigment or metal, in (b) an insulating liquid in which is disolved an extract of asphalt with a saturated hydrocarbon liquid, the developer being free of asphaltic compounds which are insoluble in the saturated hydrocarbon liquid. In the examples particles of carbon black, dyes, pigments and aluminium are used.
