METHOD FOR IMPARTING NON-FOGGING PERFORMANCE TO OPTICAL ARTICLE AND NON-FOGGING OPTICAL ARTICLE

摘要

PROBLEM TO BE SOLVED: To impart a non-fogging effect excellent in scuffing and wear resistances and durability to an optical article such as eyeglass or a windowpane without impairing its surface hardness and optical characteristics such as antireflection property. SOLUTION: The surface of an oxide-base optical article is treated with a silane coupling agent containing an unsaturated double bond group, a thiol with a structure having a hydrophilic group in a side chain or between hydrophobic groups and forming a crosslinked structure between the hydrophobic groups is fixed on the treated surface by an ene-thiol reaction by photo graft polymerization, radiation graft polymerization, graft polymerization in an aqueous solution or another method and then crosslinking is carried out to impart non- fogging performance excellent in durability to the optical article.
