Process for making a décor paper having improved optical performance

A dcor paper is prepared from a dispersion having improved optical performance, wherein the dispersion contains a TiO.sub.2 particle slurry; paper pulp; and a cationic polymer. The TiO.sub.2 particle slurry has a treated TiO.sub.2 particle with a surface area of at least about 30 m.sup.2/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 TiO.sub.2 particle slurry described would require about 10% more treated TiO.sub.2 particle than a dispersion made with the described TiO.sub.2 particle slurry, paper pulp, and cationic polymer to achieve equivalent optical performance. These dcor papers are useful in preparing paper laminates.
