Abstract: A composition for producing an electrically conductive layer according to a slotted-nozzle method includes 2-30 wt. % of a protective colloid mixture which is soluble or dispersible in water, 1-15 wt. % of a conductive carbon modification, 5-50 wt. % of metal-coated particles, 50-90 wt. % of an aqueous solvent, the dynamic viscosity of the conductive composition being less than 400 mPa·s, wherein the composition comprises 0.1-10 wt. % of an ethylene-vinyl acetate copolymer. The electrically conductive layer being one or both of a pair of conductive layers having a luminous layer with electroluminescent pigments arranged therebetween in an electroluminescense device or related method for producing an electroluminescense device.

Abstract: The invention relates to a luminous element having a luminous layer which comprises electroluminescent particles and a water-dispersible or water-soluble protective colloid.

Abstract: The invention relates to a security material comprising a carrier and at least one photochromic Protein and/or a mutein of a photochromic protein. The security material is characterized in that it comprises at least one irreversible photosensitive layer on the carrier, and the at least one photochromic protein and/or mutein is contained at least in the at least one photosensitive layer and/or in an optional additional layer. The inventive security material is also characterized in that it is highly forgery-proof, the photochromic biomolecule cannot be removed therefrom in a usable form, and the photochromic biomolecule does not need to be supplied to a large group of clients.
