Description

  

  Lichtdurchlässiger,     Ultraviolettstrahlen    absorbierender Körper.    Gegenstand der Erfindung ist ein licht  durchlässiger,     Ultraviolettstrahlen    absorbie  render Körper, der dadurch     gekennzeichnet     ist, dass er wenigstens     eine    Schicht aufweist  aus     einem    Produkt, das eine transparente  Substanz und mindestens ein     Ogymethylcu-          marin    enthält.  



  Erfindungsgemässe     Körper    werden bei  spielsweise erhalten,     wenn    man eine Glas  scheibe oder eine Scheibe aus einem     andern     transparenten Material mit     Zelluloseester-          lack,    oder     gewöhnlichem    Firnis überzieht,  dem     mindestens    ein     Ogymethylcumarin,    ins  besondere     4-Methyläsculetin    oder     4-Methyl-          umbelliferon,

          zweckmässigerweise    unter     Mit-          verwendung    eines alkalisch reagierenden  Stoffes als     Lösungsvermittler    für das     Ogy-          methylcumarin,    einverleibt wurde. Neben dem       Ogymethylcumarin    können auch noch andere       Absorptionsmittel    für     Ultraviolettstrahlen,     wie zum Beispiel     Chininsalze,    verwendet wer  den.  



  Produkte, wie sie zur Herstellung des  erfindungsgemässen lichtdurchlässigen, Ultra-         violettstrahlen    absorbierenden Körpers Ver  wendung finden können, sind im schweizeri  schen Patent Nr. 193348 beschrieben.  



  Ein lichtdurchlässiger Körper, zum Bei  spiel eine Glasplatte,     insbesondere    Fenster  scheibe, kann     erfindungsgemäss    sowohl     ein-          als    auch beidseitig mit dem     Ultraviolettstrah-          len    absorbierenden Produkt     überzogen    sein.  Der erfindungsgemässe Körper kann auch ein       Verbundkörper    aus zwei oder mehr Glas  platten sein, bei dem die. absorbierende  Schicht die Bindung zwischen den einzelnen       Glasplatten    bewirkt.

   Unter Umständen ist es  zweckmässig, die     Ultraviolettstrahlen    absor  bierende     Überzugsschicht    des lichtdurchläs  sigen Körpers durch einen besonders bestän  digen Lacküberzug zu schützen.



  Translucent body that absorbs ultraviolet rays. The subject matter of the invention is a light-permeable, ultraviolet radiation-absorbing body which is characterized in that it has at least one layer made of a product which contains a transparent substance and at least one ogymethylcumin.



  Bodies according to the invention are obtained, for example, if a glass disk or a disk made of another transparent material is coated with cellulose ester varnish or conventional varnish to which at least one ogymethylcoumarin, in particular 4-methylasculetin or 4-methyl umbelliferone,

          It was expediently incorporated using an alkaline substance as a solubilizer for the ogymethylcoumarin. Besides the ogymethyl coumarin, other ultraviolet ray absorbers such as quinine salts can also be used.



  Products that can be used to produce the translucent, ultraviolet ray absorbing body according to the invention are described in Swiss Patent No. 193348.



  According to the invention, a transparent body, for example a glass plate, in particular a window pane, can be coated on one side as well as on both sides with the product which absorbs ultraviolet rays. The inventive body can also be a composite body made of two or more glass plates, in which the. absorbent layer creates the bond between the individual glass plates.

   Under certain circumstances, it is useful to protect the ultraviolet rays absorbing coating layer of the lichtdurchläs denominated body by a particularly persistent lacquer coating.
