The present invention has the object to provide a hybrid filmnhaving good abrasion-resistant and defogging properties, annantireflection film comprising it, an optical product, and anmethod for restoring the defogging property of the hybridnfilm. n The above object is achieved by means of a hybrid film havingna defogging property, which is obtained through vaporndeposition of an organic compound having a hydrophilic groupnand a reactive group along with silicon dioxide or withnsilicon dioxide and aluminium oxide; an antireflection filmnto be formed on a substrate having the hybrid film as thenoutermost layer opposite to the substrate; an optical productncomprising a plastic substrate and the antireflection filmnhaving the hybrid film; and a method for restoring thendefogging property of the hybrid film of the optical product,nwhich comprises washing of the hybrid film. |
