ABSTRACT:
A method for treating a surface of a substrate to render it nonfogging and the resulting article formed by the treatment. A thin film coating of a block copolymer containing alternating blocks of polyurethane and a hydrophilic copolyacrylic is adhered to the surface to be made nonfogging. The copolyacrylic is a copolymer of a hydroxy substituted acrylate and an ethylenically unsaturated acid such as acrylic acid. By varying the weight ratio of polyetherurethane/copolyacrylic it is possible to vary the flexibility of the coating and hence to widen the range of substrates to which the treatment is applicable, e.g., from flexible wrapping material to rigid mirrors.
