Abstract
An inkjet ink includes a) an aqueous medium; and b) capsules composed of a polymeric shell surrounding a core; wherein the capsules are dispersed in the aqueous medium using a dispersing group covalently bonded to the polymeric shell; the core contains one or more chemical reactants capable of forming a reaction product upon application of heat and/or light; the polymeric shell includes a polymer selected from the group consisting of polyureas, polyesters, polycarbonates, polyamides, and melamine based polymers and copolymers thereof; and the capsules have an average particle size of no more than 4 μm as determined by dynamic laser diffraction.
