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