Title:
プラスチックレンズ
Document Type and Number:
Japanese Patent JP4750694
Kind Code:
B2
Abstract:
A coating agent composition obtained by mixing fine inorganic oxide particles, a polymerizable alkoxysilane compound, a polymerizing catalyst, an acid aqueous solution and an organic solvent, and satisfying the following conditions (1) to (3): (1) the polymerizing catalyst is at least partly an acetylacetonato complex; (2) a ²-dicarbonyl compound (excluding acetylacetonato complex) having two carbonyl groups in the molecule via a carbon atom, is further contained as a catalyst stabilizer; and (3) the fine inorganic oxide particles and the alkoxysilane compound are contained in a total amount of 23 to 40% by mass. The coating agent composition is capable of forming a cured film having excellent properties such as abrasion resistance on the surfaces of plastic ophthalmic lens through the curing conducted at a low temperature for a short period of time, and does not affect the color tone of the lens material even when it is directly applied to the surfaces of the plastic lens material that contains a coloring matter, such as sunglass lenses.
