The present disclosure describes monomeric compounds and polymeric compounds that comprise at least one of the monomeric compounds and compositions that can be included in a coating composition for coating a substrate. The coated substrate may have biocidal activity or the potential for increased biocidal activity. The potential for increased biocidal activity may be realized by exposing the coated substrate to one or more further agents, such as one or more halogens. The monomer compound comprises (i) one or more cationic centers, (ii) an N-halamine precursor group, and (iii) at least one coating-incorporation group (CIG). The CIG bonds with another component within the coating composition or alternatively the CIG may bond with a component of the substrate. The CIG of the composition may incorporate the monomer into the coating composition, may incorporate the coating composition onto the substrate, or the CIG may perform both functions.
