There are provided charge control compounds having the general structure:
wherein
R1 is selected from the group consisting of hydrogen; alkyl containing from 1 to 20 carbons; cycloalkyl containing from 3 to 18 carbons;
unsubstituted aromatic ring systems; aromatic ring systems substituted with one or more alkyl, halo, nitro, cyano, hydroxy, alkoxy, carboxy, carboalkoxy, amino, dialkylamino, acyl, trihalomethyl or alkysulfonyl; and heteroaromatic ring systems; said ring systems having a solitary ring or 2 to 3 linked or fused rings, and containing from 3 to 34 carbons; alkanoyl; alkoxycarbonyl; aminocarbonyl; alkylaminocarbonyl; aralkylaminocarbonyl; alkylsulfonyl; aroyl; aryloxycarbonyl; arylaminocarbonyl; arylsulfonyl; or aroyl, aryloxycarbonyl, arylaminocarbonyl, aralkylaminocarbonyl or arylsulfonyl substituted with one or more alkyl, hydroxy, alkoxy, carboxy, carboalkoxy, nitro, halo, cyano, amino, dialkylamino, acyl, trihalomethyl or alkylsulfonyl; and R2 and R3, which can be the same or different, are independently selected from the group consisting of alkyl containing from 1 to 20 carbons; cycloalkyl containing from 3 to 18 carbons; unsubstituted aromatic ring systems; or aromatic ring systems substituted with one or more alkyl, hydroxy, alkoxy, carboxy, carboalkoxy, nitro, halo, cyano, amino, dialkylamino, acyl, trihalomethyl or alkylsulfonyl; heteroaromatic ring systems; said ring systems having a solitary ring or 2 to 3 linked or fused rings, and containing from 3 to 34 carbons; and R3 may also be ethenyl, unsubstituted or substituted with alkyl containing from 1 to 20 carbons or aryl containing from 5 to 10 carbons or aryl substituted with alkyl, hydroxy, carboxy, carboalkoxy, nitro, halo, cyano, amino, dialkylamino, acyl, trihalomethyl, or alkylsulfonyl.
The described charge control agents are negative charge control agents and are essentially colorless making them particularly useful in toner compositions for color electrophotography.
