Curable coating compositions and antimicrobial coatings made by curing such coating compositions

A coating composition comprising (i) one or more free radical-polymerizable monomers wherein the at least one free radical-polymerizable monomer constitutes 35-99.5% of the combined weights of (i), (ii), (iii) and (iv), (ii) at least one free radical initiator, and 0.25 to 40% by weight based on the combined weights of (i), (ii), (iii) and (iv), of a least one of (iii) and (iv), wherein (iii) is at least one phenolic compound having a molecular weight of up to 500 g/mol and/or one or more menthol isomers and (iv) is at least one non-free radical-polymerizable ammonium compound having a molecular weight of up to 1000.
