DISPERSIONS MADE FROM TREATED INORGANIC PARTICLES FOR MAKING DECOR PAPER HAVING IMPROVED OPTICAL PERFORMANCE |
摘要 |
The disclosure provides a dispersion for making décor paper having improved optical performance without negatively impacting mechanical strength comprising a TiO2 particle slurry comprising a treated TiO2 particle having a surface area of at least about 30 m2/g, and a cationic polymer; wherein the treatment comprises 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; paper pulp; and a cationic polymer; wherein the cationic 1.5 polymer in the slurry and the cationic polymer in the dispersion are compatible; wherein for equal optical performance, the amount of treated TiO2 particle in the dispersion is reduced by about 10% when compared to a dispersion not comprising the treated TiO2 particle of (a). These dispersions are useful in making décor paper that may be used in paper laminates. |

1. A dispersion for making décor paper having improved optical performance without negatively impacting mechanical strength comprising:
(a) a TiO2 particle slurry comprising a treated TiO2 particle having a surface area of at least about 30 m2/g, and a cationic polymer; wherein the treatment comprises 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: (b) paper pulp; and (c) a cationic polymer; wherein the cationic polymer in the slurry and the cationic polymer in the dispersion are compatible; wherein for equal optical performance, the amount of treated TiO2 particle in the dispersion is reduced by about 10% when compared to a dispersion not comprising the treated TiO2 particle of (a). |
