Abstract
1398025 Electrostatic developer XEROX CORP 9 Nov 1972 [11 Nov 1971] 51804/72 Heading G2H [Also in Division C3] An electrostatic developer comprises a resin and a diarylide yellow colourant satisfying the Formula. The resin is preferably transparent. It may be a styrene-butyl methacrylate copolymer, a styrene-vinyltoluene copolymer, a styreneacrylate copolymer, a polystyrene resin or a polymeric esterification product of a dicarboxylic acid and a diol comprising a diphenol. The resin and colourant are compounded in toner particles, and mixed with carrier particles for cascade or magnetic brush development. Lists of resins and carrier particle materials are given.
