ABSTRACT:
This invention relates to rosin carboxypyrrolidinone adducts. In particular, this invention relates to water-soluble resins derived from the reaction product of a modified rosin with a hydroxyl-containing carboxypyrrolidinone derivative. These resins can be used to make acrylic latex compositions which can, in turn, be utilized to produce water-based flexographic and gravure ink formulations.
