(European Patent Organization). CODEN: EPXXDW. CLASS: ICM: G03G009-135. APPLICATION: EP 91-107386 7 May 1991. PRIORITY: US 90-522282 11 May 1990. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A pos. charged electrostatic liq. developer is described consisting essentially of (A) a nonpolar liq. 4855-39-4 and 18050-00-5 which are cas registry numbers are also used here. having a Kauri-butanol value of less than 30, present in a major amt., (B) thermoplastic resin particles having an av. by area particle size of less than 10 mm, (C) a charge director compd., and (D) 31 sulfonic or sulfamic acid compd. of the formulas: (1) RSO3H, and (2) RNHSO3H [R is alkyl, aryl] which is sol. in an amt. of 30.5% based on the wt. of component (C) in a mixt. of components (A) and (C). The liq. developer is useful in copying, color proofing, digital color proofing, making lithog. printing plates, and resists. .
