Abstract
1313350 Electro-photography IWATSU ELECTRIC CO Ltd 29 Sept 1970 [23 Oct 1969] 46214/70 Heading G2H A liquid developer comprising a dispersion of a colorant in an insulating liquid also comprises asphalt and a synthetic resin. 5-75% colorant, 1-90% asphalt and 10-99% resin may be employed. The colorant may have a particle size of less than 10 microns. Resins exemplified are soy bean oil-alkyd resin, terpene resin, and vinyltoluene oil.
