MODIFIED PEARLESCENT PIGMENT AND ITS PRODUCTION

摘要

The invention relates to a modified pearlescent pigment and its production process by post-coating. The pigment includes a sheet substrate, titanium dioxides coated on the substrate and hydrates of metal phosphate (s) and metal oxide (s) on the titanium dioxide coating. This pigment could keep color staff e during its use and exhibit excellent discoloration resistance caused by ultraviolet as well as prevent yellowing during its use in polyolefin compositions containing antioxidant.
