Abstract
The present invention relates to a composition that, when applied to a substrate, forms an adherent, transparent, water insoluble polymeric film on the substrate surface that provides sustained antimicrobial disinfecting action for prolonged periods, without the necessity for reapplication. The coating provides surface disinfecting action by a contact-killing mechanism, and does not release its components into contacting solutions at levels that would result in solution disinfection. The polymeric film formed by the composition of the invention can be removed by treatment with dilute alcoholic base.
