| abstract |
The present invention relates to a printing ink, preferably a 3D printing ink, wherein the printing ink comprises at least one radiation curable component and, optionally, at least one dye, and the radiation curable component comprises at least one monomer from the group consisting of (meth) acrylate monomers, epoxy monomers, vinyl monomers and allyl monomers. The invention moreover relates to the use of a printing ink, preferably a 3-D printing ink, for producing a spectacle lens. Furthermore, the invention relates to a spectacle lens comprising at least one coloured and/or effect-imparting layer, wherein the spectacle lens is obtainable by a unit-by-unit arrangement of at least one volume element of a printing ink, preferably a 3D printing ink, comprising at least one radiation curable component and the coloured and/or effect-imparting layer comprises at least one volume element of a printing ink having at least one dye. |
