    摘要: The present invention relates to photochromic 2H-naphtho[1,2-b]pyrans as well as their use in synthetic resins of all types, especially for ophthalmic purposes. In particular, the present invention relates to photochromic naphthopyran compounds, for which a further ring system is bonded to the f side of the naphthopyran. The inventive photochromic dyes generally have the general formula (I) wherein n, R1, R2, R3, X, B and B′ are defined as in claim 1. The inventive compounds are distinguished by good darkening and decolorizing properties and a very good service life.

    摘要: What is described here are photochromic naphthopyrane dyes with different substituents whose properties can be set by controlled selection of the substituents. In this manner it is possible to take an influence on the migration characteristics, the absorption characteristics and the brightening rate and kinetics. The inventive compounds display good darkening and brightening properties at a very good service life.The invention excels itself by the fact that a method is made available which is substantially improved over prior art, in addition to the surprising influence on specific properties of the inventive compounds. The described compounds are suitable for application in synthetic materials of any kind.A photochromic object is also the subject matter of the invention, which comprises one or several photochromic naphthopyrane dyes as well as at least one polymer material, with the photochromic object being producible by mass-dyeing or superficial dyeing.
