Definitions

  • the invention relates to an optical element with a phototropic coating, for example a sun protection spectacle lens.
  • Optical elements with phototropic coatings i.e. Coatings, the coloring of which changes in intensity and color impression in accordance with the ambient lighting, are known, for example, from DE-OS 29 26 255.
  • This document describes two ways in which a phototropic coating can be applied to an optical element.
  • a mixture of the phototropic substance and an optically clear plastic material is produced and this mixture is applied to the optical element.
  • the phototropic substance is first dissolved in a solvent; the optical element is then immersed in the solution for several hours.
  • Coating is that the coatings are either lengthy to produce, adhere poorly and / or the optical quality of the optical element is reduced.
  • the object of the invention is to develop an optical element with a phototropic coating in such a way that the easily applied coating adheres well and does not impair the optical quality of the element.
  • This object is achieved in that the coating consists of a lacquer in which one or more phototropic substances are introduced.
  • the lacquer can be applied to the front and back of the optical element or only on one side.
  • a protective lacquer is used as the lacquer, as is usually used to protect plastic glasses against mechanical and / or other effects.
  • This has the additional advantage that no additional operation is required to apply the phototropic coating in plastic glasses; rather, the optical element, for example a spectacle lens, is given the phototropic coating by the application of the protective lacquer, which is in any case necessary to protect against external influences.
  • the lacquer can have several layers, the phototropic coloring of which can be different. Mixed colors and / or colored patterns can be generated in this way.
  • one or more phototropic substances can also be introduced into the optical element.
  • phototropic compounds such as saturation transmission, kinetics of darkening and brightening, temperature dependence and lifespan of the phototropic effect, transmission in the brightened state and also the color impression depend to a large extent on the chemical environment of the phototropic compounds, i.e. the matrix into which phototropic substances are introduced.
  • the many phototropic substances if they are introduced into a lacquer according to the invention, have a longer service life with regard to the phototropic effect than when they are introduced, for example, into the plastic material of the optical element.
  • the optical element and / or the coating can further be colored according to claim 4 additionally in a manner known per se non-phototropically.
  • the optical element is a spectacle lens
  • the lens may not be optically clear, but rather be provided with a certain "initial absorption".
  • both the phototropic and the non-phototropic coloring can be homogeneous or partial.
  • the coloring can be gradual, for example in such a way that the coloring decreases from the top edge of the glass downwards.
  • the phototropic or photochromic substances can be introduced either gradually in the coating or in the optical element itself.
  • the matrix of the phototropic compound and thus the properties of the phototropic compound for example with regard to the kinetics of the coloring, life To influence saturation transmission, color etc.
  • stabilizers to the phototropic lacquer which prevent photooxidative and / or photolytic aging or destruction of the phototropic compounds introduced into the lacquer and / or the optical element, for example by atmospheric oxygen and / or UV rays or at least delay it.
  • the stabilizers can UV absorbers of the usual type, such as benzophenone, benzotriazole Be acrylic acid derivatives.
  • the stabilizers described in DE-OS 33 10 388 can be used, for example.
  • phototropic or photochromic compounds or substances can be used as phototropic or photochromic compounds or substances, as described, for example, in US Pat. Nos. 3,562,172 and 3,578,602 or in DE-OS 29 36 255.
  • the phototropic compounds according to claim 12 are particularly advantageous with regard to temperature stability and service life.
  • Elements needs the phototropic substance in the case of the usual diffusion coloring of the CR 39 material over eight times as long to lighten up to half the darkening than when the inventive introduction.
  • Polysiloxane base with a layer thickness of approx. 3 ⁇ m was colored phototropically.
  • the specified transmission values are V-weighted.
  • Brightening is significantly faster, a brightening to 70% of the maximum transmission is achieved in 2.5 minutes instead of only in 20 minutes.
  • Substances lie in the fact that already known phototropic compounds can be used as sun protection filters at all or even at low temperatures.

Abstract

Le revêtement se compose d'une laque comportant une ou plusieurs substances phototropiques. La laque peut présenter plusieurs couches dont la coloration phototropique peut différer. L'élément optique peut en outre comporter une ou plusieurs substances phototropiques. De plus, l'élément optique et le revêtement peuvent posséder une coloration non-phototropique d'une manière connue en soi.
