摘要： The invention relates to specific photochromic phenanthropyrans and the use thereof in all types of plastics, particularly for ophthalmic purposes. The invention especially relates to photochromic compounds which are derived from 2H-phenanthro[2,1- b]pyrans and 3H-phenanthro[3,4-b]pyrans and are provided with particularly long wavelength absorption maxima in the open form while being colorless in the non-excited state.

摘要： The invention relates to specifically photochromic 3H-naphtho[2,1-b]-pyran derivatives of formula (I), where the groups R1-R7 and B' have the meanings given in the description and use thereof in plastics of all types, in particular for ophthalmic purposes. The invention particularly relates to photochromic compounds derived from 3H-naphtho[2,1-b]-pyrans which have particularly long-waved absorption maxima in the open form. On use in phototropic glasses, essentially blue colour tones can be achieved which also have a high darkening capacity.

摘要： The invention relates to specific photochromic 3H-naphtho[2,1-b]-pyrane derivatives and to the use of the same in all types of plastic, especially for ophthalmic purposes. The invention especially relates to photochromic compounds derived from 3H-naphtho[2,1-b]-pyranes, said compounds having especially long-wave absorption maxima in the open form thereof, enabling violet to blue tints to be obtained when used in phototropic lenses.

摘要： The invention relates to specific photochromic pyran derivatives and the use thereof in all forms of plastic, especially for ophthalmic purposes. The invention especially relates to spiro compounds with a fluorene structure which are derived from naphthopyrans. Said compounds are known as spirofluorenopyrans . According to the invention, only one strong electron-pushing or electron-attracting group is introduced in each case into specific positions on the periphery of the pyran dye in order to obtain photochromic compounds which are characterised, in their excited form, by an enlarged colour spectrum accompanied by comparatively good brightening speeds and behaviour in the shelf life test.
