CA 2266707

Disclosed are certain substituted styrenic binder resins and ink compositions comprising such binder resins. An example of the binder resin is formula (I), wherein X is OR1 wherein R1 is C1-C6 haloalkyl, C1-C6 hydroxyalkyl, C1-C6 alkylcarbonyl, C1-C6 aminoalkyl, cyano C1-C6 alkyl, or C1-C6 alkoxy C1-C6 alkyl; or X is NR2R3 wherein R2 and R3 are hydrogen, C1-C6 alkyl, C1-C6 haloalkyl, C1-C6 hydroxyalkyl, C1-C6 alkylcarbonyl, C1-C6 aminoalkyl, cyano C1- C6 alkyl, or C1-C6 alkoxy C1-C6 alkyl. Also disclosed are jet ink compositions suitable for jet printing identifying marks on substrates such as paper, glass, metal, ceramic, or plastic substrates comprising a carrier, a colorant, and a binder resin. Disclosed also are processes for printing using the inventive ink compositions.
