Abstract: Biocidal compositions including a carrier, a copper(I) salt, and a copper-assisting additive different from the carrier are provided, which in some aspects have improved antimicrobial efficacy and/or total color difference. Also provided are biocidal compositions or UV curable films thereof that exhibit high transmittance that is similar to the transmittance of an otherwise identical composition or film thereof without either the copper(I) salt or the copper-assisting additive. Also provided are biocidal additive formulations in which a copper(I) salt has a molarity of at least 20 mM.
