Abstract (en)
[origin: EP1921207A1] The invention deals with a method of making a paper with improved surface properties, characterized in that that nano-hybrid particles containing 1-99% organic nano particles of polystyrene or a styrene copolymer and 99-1% inorganic particles are applied in the wet end of the paper making process or as a solution or dry onto the wet or dried paper fiber web as well as the paper proudced by said process.
