    摘要: Disclosed is a process for the production of a photochromic object, composed of a polymer and containing at least one spirooxazin compound, having the following process steps: an acrylate monomer or a methacrylate monomer, respectively a mixture of a multiple thereof is utilized as the polymerizable monomer, the photochromic dyes as well as a polymerization initiator are mixed in the polymerizable monomer, the mixture yielded thereby is placed in a casting mold, polymerized and hardened. The present invention is distinguished by, in order to obtain a neutral gray, neutral brown or green photochromic tint of the polymerizable mixture, several photochromic dyes being added of which at least one is not a spirooxazin, and by the concentration of the spirooxazin compound(s) amounting to no more than 0.045 weight percent relative to the mass of the utilized monomer, and that of the polymerization initiator(s) amounting to more than 1 weight percent relative to the mass of the utilized monomer.

    摘要: An anti-reflection film of several layers is described for an optical element consisting of an organic material with photochromic properties.The film according to the invention is characterized by the fact that the mean reflection of the film over the spectral range between 330 nm and 380 nm is less than 4% and the mean reflection over the range between 290 nm and 330 nm is greater than 15%. This reflection behavior serves to prevent the stimulation of the photochromic effect by light with too short a wavelength from reducing the useful life of the photochromic effect. In addition, a suitable choice of the reflection properties means that a deliberate stimulation of photochromic molecules situated in certain steric positions and so influence on the kinetics and color of the photochromic effect can be obtained.

    摘要: A high refractive index, curable, synthetic resin composition comprising a core resin composition composed of a mixture of ethylenically unsaturated compounds, and an initiation system containing both photo and thermal initiators, particularly a photochromic resin composition which further includes at least one photochromic dye. Also a curing process, which includes a combination of multi-step radiation curing and thermal annealing. Articles produced of cured composition exhibit superior physical and, in appropriate cases, photochromic properties and can be easily mass produced on a commercial scale due to short processing time and use of readily available chemicals.

    摘要: Disclosed is an object made of plastic material, in particular a plastic ophthalmic lens, colored with at least one photochromic substance which is also excited by light in the UV range of the spectrum and has a higher absorption in the excited state, judged by the spectral light sensitivity of the human eye, than in the not excited state and to which, in addition, at least one UV absorbing material is added in such a concentration that darkening of the photochromic substance(s) is independent of the UV fraction of the excitation light.But rather the intensity of the darkening depends on brightness, i.e. the intensity integrated over the spectral light sensitivity of the human eye V.sub.2.
