Abstract: A process including: forming a first chlorogallium phthalocyanine (ClGaPc) in N-methyl-2-pyrrolidone (NMP) to form a ClGaPc (NMP) Type-I product; forming a second chlorogallium phthalocyanine in dimethyl sulfoxide (DMSO) to form a ClGaPc (DMSO) Type-I product; separately dry milling and then wet treating the Type-I products to form respective Type-II products; blending the Type-II products together along with a resin to form a coating mixture; and coating the mixture to form a charge generator layer in an electrostatographic imaging article.

Abstract: Disclosed is a process for preparing substituted pyridone compounds which comprises (a) admixing in the absence of a solvent (1) an amine of the formula R1nullNH2 wherein R1 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, and (2) a first ester of the formula 1 wherein R2 is an electron withdrawing group and R3 is an alkyl group; (b) heating the mixture containing the amine and the first ester to form an intermediate compound of the formula 2 (c) admixing the intermediate compound with (1) a base and (2) a second ester of the formula 3 wherein R4 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group and R5 is an alkyl group, said second ester being present in a molar excess relative to the intermediate compound, said base being present in a molar excess relative to the intermediate compound, and (d) heating the mixture containing the intermediate compound, the second ester, and the base to form a pyridone compound of the formula 4 or a salt thereof. Also disclosed is a process for preparing diazopyridone colorants which comprises preparing a pyridone compound by the above process and reacting the pyridone compound with a diazonium salt to form a diazopyridone compound.

Abstract: Disclosed is a process which comprises (a) reacting allyl bromide with diethyl amine in a molar ratio of at least about 1 mole of allyl bromide per about 1.15 moles of diethyl amine and in a molar ratio of no more than about 1 mole of allyl bromide per about 2 moles of diethyl amine, thereby generating allyl diethyl amine in a monomer reaction mixture; (b) subsequently filtering the monomer reaction mixture to remove impurities; (c) subsequently reacting the allyl diethyl amine with allyl bromide, thereby generating solid diallyl diethyl ammonium bromide; (d) subsequently isolating the solid diallyl diethyl ammonium bromide; (e) subsequently dissolving the diallyl diethyl ammonium bromide in a solvent and adding thereto a polymerization initiator to form a polymerization reaction mixture; (f) subsequently heating the polymerization reaction mixture in a vessel equipped with a reflux condenser to a temperature of from about 90 to about 100null C., thereby generating poly(diallyl diethyl ammonium bromide); and (g) subsequently optionally isolating the poly(diallyl diethyl ammonium bromide) from the polymerization reaction mixture.
