Verfahren zum Herstellen funktioneller Oberflaechenbereiche auf einem Flaechensubstrat

EP 2051147 A2 UPAB: 20090602 NOVELTY - Preparing local, functional surface areas on surface substrate, comprises: providing functional particle, in the form of surface-modified silica-nanoparticle from e.g. plastic with molecular shaped surface existing functional particle, and toner particle containing at least a drying solvent; applying the functionalized toner particle on the surface substrate by a laser printing process; and fixing the functionalized toner particle on the surface substrate for the formation of local surface area from resolidified, functional toner. DETAILED DESCRIPTION - Preparing local, functional surface areas on a surface substrate, comprises: providing a functional particle, in the form of a surface-modified silica-nanoparticle from plastic with a molecular shaped surface existing functional particle, elastomer particle and/or hydraulic gel particle, which exhibits an average diameter of 50 nm to 5 mu m, and a toner particle containing at least a drying solvent and a diameter of 1-50 mu m, where the toner particle is a functionalized toner particle; applying the functionalized toner particle on the surface substrate by a laser printing process, where the functionalized toner particles locally adhered to a photo roll by a roll pressure is transferred to a local surface area of the surface substrate; and fixing the functionalized toner particle on the surface substrate for the formation of local surface area from resolidified, functional toner. USE - The process deals with the preparation of local, functional surface areas on a surface substrate. ADVANTAGE - The process is easy and inexpensive. The local, functional surface area exhibits user-specific technical, chemical or biological properties
