Abstract
Official abstract text for this publication.
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 β-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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A plastic lens obtained by forming a cured film comprising a cured product of a coating agent composition on surfaces of a plastic lens material that contains a photochromic compound as a coloring matter, with the proviso that the content of fine inorganic oxide particles in the cured film is 40 to less than 60% by mass of a solid component in the composition and the content of a hydrolyzed product of an alkoxysilane compound in the cured film is 40 to…
