Definitions

  • the present invention relates to specific photochromic phenanthropyrans and their use in plastics of all kinds, in particular for ophthalmic purposes.
  • the present invention relates to photochromic compounds derived from 2H-phenanthro [2,1-b] pyrans and 3H-phenanthro [3,4-b] pyrans, which have particularly long-wave absorption maxima in the open form, but in the non-excited state Are still colorless.
  • the dyes known in the prior art frequently have an insufficiently long-wave absorption in the excited as well as in the non-excited state. This also leads to problems when combined with other photochromic dyes.
  • the dyes available in the prior art often have an insufficient lifespan. As a result- however, such sun protection glasses show an insufficient durability. The latter is noticeable in rapidly declining performance and / or strong yellowing.
  • 3H-Naphthopyrans derived from 2-naphthols and their higher analog derivatives derived therefrom by annulation are a group of photochromic dyes whose long-wave absorption maximum of the excited form is predominantly in the spectral range from 420 nm to 500 nm and thus a yellow, orange or convey a red-orange color impression (see US-A-5,869,658 and US-A-6,022,495).

  • 3H-Naphtho [2,1-b] pyrans with Aryl substituents in the 6-position are also described in WO 99/31082.
  • the effect of aryl substitution in the 6-position on the longest-wave absorption maximum of the unexcited as well as the excited form is very small with these compounds.
