  • Patent number: 8231971
    Abstract: The invention relates to an anti-fog coating for a surface of a substrate comprising: a first polymer layer resulting from covalently bonding a polyanhydride polymer to said surface; and a second polymer layer resulting from covalently bonding a polymer selected from the group consisting of polyvinyl alcohol, partially hydrolyzed polyester, polyether and cellulose derivative; said surface having nucleophilic groups. A substrate having an anti-fog coating, as well as a process for preparing said anti-fog coating to the surface of a substrate is also provided.
    Type: Grant
