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.
A hybrid film that is obtained by vapor deposition of at least one organic compound having a hydrophilic group and a reactive group and having a number average molecular weight ranging from 150 to 1500 g/mol. along with silicon dioxide or with a combination of silicon dioxide and aluminum oxide.
An optical product comprising a plastic substrate, an antireflection film and a hard coat film between the plastic substrate and the antireflection film, wherein the antireflection film comprises a hybrid film, which is obtained through vapor deposition of at least one organic compound having a hydrophilic group and a reactive group along with silicon dioxide or with a combination of silicon dioxide and aluminum oxide,
A method of making an optical product, comprising forming an antireflection film on a plastic substrate, the antireflection film comprising a hybrid film that is obtained through vapor depositing at least one organic compound having a hydrophilic group and a reactive group along with silicon dioxide or with a combination of silicon dioxide and aluminum oxide.
