Abstract: Provided is an emulsion that includes a water phase and a resin containing phase. The emulsion is prepared from a mixture comprising water, a surfactant, a resin that includes an acidic moiety, and an organic compound having at least two different moieties. Each of the two moieties have a single functionality or dual functionality. The single functionality and the dual functionality are selected from a capability to neutralize the acidic moiety of the resin, a capability to form a hydrogen bond, or both.
