ANTIMICROBIAL COATING

The present invention relates to a process for producing an antimicrobial coating on a glass substrate, an antimicrobial coated glass substrate prepared by the process and use thereof, the process comprising the steps of: i) providing a glass substrate having a first surface and a second surface; ii) providing a silicon containing solution and a particle containing solution; iii) mixing together the silicon containing solution and the particle containing solution to form a silica coating composition; iv) contacting at least said first surface of the substrate with the silica coating composition to deposit a layer of silica on the glass substrate; and iv) curing the silica coating composition deposited on the glass substrate to form a silica matrix coating layer, wherein the particles are deposited on and/or within the silica matrix coating layer wherein the particles are deposited on and/or within the silica matrix coating layer in an amount of from 0.1 to 20% by weight.
