Abstract: Thin films which contain a defined concentration of dye per unit area and are useful as layer elements, e.g. for optical filters, are prepared by spreading an oleophilic dye which is soluble in an organic water-immiscible solvent and an organic polymer dissolved in an organic solvent as a thin film at the water/air interface and, after the solvent has evaporated, transferring said film by the Langmuir-Blodgett technique to a solid base material.
