摘要：
A pigmented vinyl chloride composition is provided which has a whitening and opacifying package comprising titanium dioxide and a titanium dioxide replacement/extender. The replacement/extender replaces up to 30 percent by weight of the titanium dioxide and yet maintains one or more selected optical property as if the whitening and opacifying package were pure titanium dioxide. These optical properties include the Yellowness Index, the DE* value and the percentage light transmittance. The extender is one or more of an alkaline earth metal titanate, lanthanide titanate, or aluminum titanate.
