The advantages and disadvantages of all kinds of waterborne UV resins and their synthetic methods were introduced in detail, including waterborne polyacrylate, aqueous polyester acrylate, waterborne epoxy acrylate, waterborne polyurethane acrylate and so on. The research progresses in hyperbranched technology, organic-inorganic hybrid system, dual-curing procedure and epoxy acrylate-urethane acrylate composite system of waterborne UV-curing resins were reviewed. The applications of waterborne UV resin were briefly introduced and its future directions were forecasted as well.
