Abstract (en)
[origin: WO2007085337A1] The instant invention relates to a process for the production of optically brightened paper by treating the pulp suspension with an optically brightened filler composition comprising optically brightened plastic fibres, preferably polyester fibres, which leads to a surprising high lightfastness of the resulting paper.
