Method for the surface treatment of a titanium dioxide pigment |
| 摘要 |
A method and material for improved TiO2 pigment for paper and laminates is described. Phosphorous, titanium, and aluminum compounds are successively added to a TiO2 pigment suspension. Resulting pigments show improved greying resistance and hiding power over prior art pigments, and show improved results as pigments in tests of paper and laminates.
