Abstract
1439626 Liquid electrostatic developer GAF CORP 8 Oct 1973 [1 Nov 1972] 46813/73 Heading G2H An electrostatic liquid developer comprises an electrically insulating carrier liquid, a pigment or colouring agent, a metallic soap and a copolymer of an alkyl vinyl ether and maleic anhydride, which acts as a dispersing agent. The pigment or colouring agent may be carbon black, dispersed in the carrier liquid, or a pigment or dyestuff, examples of which are listed. The copolymer may be poly (n-octadecyl vinyl ether-maleic anhydride), the carrier liquid maybe a hydrocarbon and the soap may be zirconium octoate. Carrier liquids, soaps and copolymers which can be used are listed.
