Aqueous ink jet ink compositions can be used for ink jet printing colored or invisible images on receiver elements. These compositions contain a polymeric agent comprising core-shell polymeric particles. The core of the particles comprises a hydrophobic polymer having an acid number less than 10. The shell of the particles comprises a hydrophilic polymer having an acid number of at least 70. The weight ratio of the core to the shell is at least 50:50 and up to and including 90:10. Such compositions can be used in various ink jet printing systems including drop on demand and continuous ink jet printing systems.
