ABSTRACT:
Hybrid films, such as those having good abrasion-resistance and defogging properties, antireflection films including it, optical products, and methods for restoring the defogging property of the hybrid films are disclosed. The hybrid films having a defogging property may be obtained through vapor deposition of an organic compound having a hydrophilic group and a reactive group along with silicon dioxide or with silicon dioxide and aluminum oxide. The antireflection film may be formed on a substrate having the hybrid film as the outermost layer opposite to the substrate. The optical product may comprise a plastic substrate and the antireflection film having the hybrid film. A method for restoring the defogging property of the hybrid film of the optical product may include washing the hybrid film.
