Abstract

1,265,936. Electrostatic liquid developer. GAF CORP. Nov.9, 1970 [Nov.10, 1969], No.53194/70. Heading G2H. A positive working liquid electrostatic developer comprises a pigment, as fixer, charge control agent and dispersant a copolymer of maleic anhydride and an alkyl (16-22 c) vinylether and a carrier liquid e.g. a hydrocarbon. Fixers such as rosin esters, modified rosin esters, rosin modified phenol formaldehyde and rosin -modified maleic anhydride polyhydric alcohol resins may be added.
