Abstract

PROBLEM TO BE SOLVED: To impart antifogging performances excellent in persistency, antifouling property and water-burning resistance to the surface of an optical part containing primarily oxides, by treating the surface with a silane coupling agent having an unsaturated double bond and fixing thereto a thiol having a hydrophilic group in the side chain or in the middle part of the hydrophobic group by the ene-thiol reaction to render the surface hydrophilic. SOLUTION: Optical parts containing primarily oxides on the surface may preferably include glass optical parts, synthetic resin lenses with antireflective inorganic coat films, or synthetic resin lenses with hard coat layers and antireflective inorganic coat films. The surface containing the oxides is treated with a silane coupling agent having an unsaturated double bond (e.g. vinyl trichlorosilane), and then a thiol having a hydrophilic group in the side chain or in the middle part of the hydrophobic group (e.g. thiomalic acid) is reacted with the unsaturated double bond present on the surface by the ene-thiol reaction to fix it to the surface and thereby to render the surface hydrophilic.

In the case of an optical article made of glass containing silicon oxide as a main component, there is no major problem in abrasion resistance. However, an optical article made of a synthetic resin is easily damaged and the abrasion resistance must be improved. In order to improve the wear resistance of the synthetic resin, a hard coat treatment is often performed. In particular, a hard coat containing colloidal silica is effective and widely used. In the case of a spectacle lens or the like, an antireflection film made of an inorganic substance is formed on the surface to improve the optical characteristics. A low refractive index layer is formed as the uppermost layer of the antireflection film, but silicon dioxide is widely used in terms of durability and ease of handling. As described above, silicon oxide is often used for the improvement of abrasion resistance and the antireflection film, and silicon oxide is often present on the surface of not only inorganic glass but also optical articles made of synthetic resin. . Even when a film made of an organic material is used as the anti-reflection film, if colloidal silica is contained in the uppermost layer, silicon oxide is present on the surface.
