Abstract
1,243,532. Liquid electrostatic developer. EASTMAN KODAK CO. Aug. 29, 1968 [Sept. 1, 1967], No.41239/68. Heading G2H. A liquid developer for electro-photography comprises an insulating carrier liquid e. g. cyclohexane or n-decane having dispersed therein a mixture of an alkyd resin or a maleic, pentaerythritol, styrene, glyceryl phthalate linseed oil, or linseed oil modified alkyd resin binder, a first pigment acting as charge control agent comprising a phthalocyanine, a second pigment e. g. carbon black and channel blacks both pigments having an electrostatic charge of the same polarity and rosin, hydrogenated rosin or an ester thereof as a dispersing agent. The carrier liquid may comprise a flammability control agent e.g. chlorinated fluorinated alkanes. In preparation the pigments and resin are subject to high shear rolling. A development electrode may be employed.
