Abstract:
An electrostatographic toner particle composition comprising an organic binder polymer and a dye having the structure wherein R1 represents hydrogen or an alkyl group containing 1 to about 4 carbon atoms, R2 and R3 each individually represents hydrogen, a substituted or unsubstituted alkyl group containing 1 to about 12 carbon atoms, a cycloalkyl group containing 5 to 7 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted pyridyl group, an alkanoyl group containing 2 to about 12 carbon atoms, an alkoxycarbonyl group containing 2 to about 12 carbon atoms, an alkylsulfonyl group containing 1 to about 12 carbon atoms, a cycloalkylsulfonyl group containing 5 to 7 carbon atoms, a substituted or unsubstituted phenylsulfonyl group, a substituted or unsubstituted pyridylsulfonyl group, a substituted or unsubstituted benzoyl group, a substituted or unsubstituted pyridylcarbonyl group, or a substituted or unsubstituted thienylcarbonyl group; or R2 and R3 together with the nitrogen atom represents a substituted or unsubstituted succinimido group, a substituted or unsubstituted phthalimido group, or a 5- or 6-membered saturated heterocyclic group; Y represents cyano group or a residue of formula COâ€”W, COâ€”OW or COâ€”NHW, wherein W represents hydrogen, a substituted or unsubstituted alkyl group containing 1 to about 8 carbon atoms, an alkoxyalkyl group containing up to about 8 carbon atoms, a cycloalkyl group containing 5 to 7 carbon atoms, a substituted or unsubstituted phenyl group; and Z represents a thiazole moiety II wherein R4 and R5 each individually represents a substituted or unsubstituted alkyl group containing 1 to about 8 carbon atoms, or R4 and R5 taken together with N represent a 5- or 6-membered cyclic ring system, and R6 represents a substituted or unsubstituted alkyl, aryl, alkenyl, or cycloalkyl group containing up to about 10 carbon atoms.
