Abstract
An aqueous ink composition for inkjet printing on non-porous substrates and a method for forming the same are disclosed. For example, the method includes preparing a primary polymer latex with an aromatic functional group, a hydrogen-bonding group, a flexible side-chain, and an ionic functional group and mixing the primary polymer latex with a secondary latex binder and one or more co-solvents.
