Abstract
A coating composition that is incorporated into a facemask to reduce fogging and glare is provided. For example, in one embodiment, the facemask contains a shield or visor formed from a transparent substrate having at least one surface applied with the coating composition of the present invention. The present inventors have unexpectedly discovered that one or more water-soluble organic polymers, such as ethyl hydroxyethylcellulose, may be utilized as a principal component of the coating composition to reduce fogging and glare in a simple, yet effective manner.
