Abstract

1342318 Polymeric dyes EASTMAN KODAK CO 19 April 1971 [24 Feb 1970] 22117/71 Heading C3P [Also in Divisions G2-G3] Polymeric dyes for use in electrophotographic liquid developers comprise a linear backbone chain to which are attached pendant side chains containing chromophoric groups which are the reaction product of (1) a coupling unit which comprises a cyclic or open-chain active methylene group or a phenolic nucleus containing an active methine group, the active methylene or methine group being optionally substituted by a group which is readily eliminated on coupling, and (2) an aromatic diazonium salt or oxidized colour coupling aromatic primary amine (especially a p-pherylene diamine or p-aminophenol). The examples describe the preparation of polymeric couplers by reacting copoly (p-aminostyrene/ styrene) with α-pivalyl-4-chlorosulphonylacetanilide or 1 - phenyl - 3 - (2 - chlorocarbonylbenzamido) - 5 - pyrazole or by copolymerizing styrene and N-(3,5-dichloro-2-hydroxy-4- methylphenyl) acrylamide; these couplers are then reacted with (a) oxidized 4-diethylamino-2- methylaniline or (b) 4-diethylaminobenzene diazonium ZnCl 2 double salt to form a polymeric aza or azo dye. For use in developers the polymeric dyes are converted to finely divided form and dissolved in a solvent, e.g. an isoparaffinic hydrocarbon.
