PAPER LAMINATES MADE FROM DÉCOR PAPER HAVING IMPROVED OPTICAL PERFORMANCE COMPRISING TREATED INORGANIC PARTICLES |
摘要 |
The disclosure provides a paper laminate comprising a décor paper prepared from a dispersion having improved optical performance without negatively impacting mechanical strength, wherein the dispersion comprises 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 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). |
