摘要： A photochromic optical article comprising an optical substrate having a photochromic layer which is formed on at least one surface thereof and contains a photochromic compound is dispersed in a resin, and a thin metal oxide layer formed on the photochromic layer, wherein an indenonaphthopyran compound is used as the photochromic compound, the photochromic layer having a thickness of 30 to 50 μm, and the thin metal oxide layer has a thickness of 0.01 to 10 μm. The photochromic optical article has excellent photochromic properties, effectively suppresses a decrease in the photochromic properties caused by deterioration due to oxidation and features very excellent photochromic light resistance.

摘要： 1-aryl-3,4-dihydro-1H-naphthalene-2-one is prepared by isomerizing an epoxy compound represented by the following general formula, wherein a is an integer of 0 to 5, b is an integer of 0 to 4, and R1 to R6 are hydrogen atoms or substituents such as alkyl groups, in an organic solvent in the presence of magnesium sulfate. This process makes it possible to prepare the 1-aryl-3,4-dihydro-1H-naphthalene-2-one safely and in a high yield without using highly explosive compounds such as lithium perchlorate.
