A décor paper is prepared from a dispersion having improved optical performance, wherein the dispersion contains a TiO2 particle slurry; paper pulp; and a cationic polymer. The TiO2 particle slurry has a treated TiO2 particle with a surface area of at least about 30 m2/g and a cationic polymer; the treatment is an oxide of silicon, aluminum, phosphorus or mixtures thereof; and the treatment is present in the amount of at least 15% based on the total weight of the treated titanium dioxide particle. Comparable dispersions not using the TiO2 particle slurry described would require about 10% more treated TiO2 particle than a dispersion made with the described TiO2 particle slurry, paper pulp, and cationic polymer to achieve equivalent optical performance. These décor papers are useful in preparing paper laminates.
