Abstract
A coating composition including a reinforcing agent. The coating composition may include one or more radiation-curable monofunctional monomers, one or more radiation-curable multifunctional monomers or oligomers, a photoinitiator, and a reinforcing agent. The monofunctional monomers, multifunctional monomers, and multifunctional oligomers may include acrylate groups. The reinforcing agent may be an acrylic co-polymer that includes two or more repeat units. At least one of the repeat units includes chemical groups that enable self-association of the acrylic co-polymer. Self-association of the acrylic co-polymer may improve the tensile strength of coatings formed from the coating compositions.
