    摘要： The present invention relates to a photochromic curable composition suited for the production of a photochromic cured product having excellent optical properties such as a high refractive index and a large Abbe ' s number, having favorable photochromic properties such as a large color density, and having good fatigue resistance, and to a photochromic lens obtained by curing the photochromic curable composition. The photochromic curable composition is characterized by comprising 100 parts by weight of a polymerizable monomer containing at least 10% by weight of a sulfur-containing (meth)acrylate polymerizable monomer represented by the following general formula (1),


    wherein R1, R2 and R3 may be the same or different and are hydrogen atoms or methyl groups, and n is an integer of 1 to 10,
    and 0.001 to 10 parts by weight of a photochromic compound.

    摘要： There is provided a coating composition which can be applied to a substrate such as a plastic lens so as to form a photochromic coating layer having good photochromic properties and excellent adhesion to the substrate on the surface of the substrate.
    This composition comprises, for example, as monomer components, 0.1 to 20 wt% of monomer-having a group which produces a silanol group through hydrolysis such as γ-methacryloyloxypropyltrimethoxysilane and 0.1 to 50 wt% of monomer having at least one oxycarbonyl group in a molecule. The composition can further contain a maleimide compound as a monomer component and further desirably contains an amine compound.
