    摘要： The present invention relates to photochromic fluorenopyrans with defined dibenzo[b,d]pyrano fused attachment in accordance with the general formulae (I) and (II) and to their use in polymers of all kinds, more particularly for ophthalmic purposes. The photochromic compounds of the invention are notable for two pronounced absorption bands of the open form in the visible wavelength range - that is, using dye molecules of this kind it is possible to replace two conventional photochromic dyes each with only one discrete absorption band. The compounds of the invention, moreover, combine a very long life with very high performance.

    摘要： The invention relates to a method for producing a photochromic plastic article, comprising the steps: (a) applying a layer comprising monomers, which are suited for forming a polymer, in liquid form and at least one photochromic colorant to at least one area of the inner surface of a first casting mold (GF1), which is situated in a casting packet, and partially or completely hardening the layer while forming a photochromic polymer layer (3); (b) optionally applying a protective layer (2) to the partially or completely hardened photochromic polymer layer (3) and hardening the protective layer (2); (c) pouring a casting resin (1) into the casting packet, which comprises the first casting mold (GF1) that, together with a second casting mold (GF2), forms a predetermined cavity inside the casting packet, and; (d) hardening the casting resin (1) while forming a photochromic plastic article. The invention also relates to a photochromic plastic article that can be obtained by using this method.
