Resumen
A process for the preparation of amorphous aluminum phosphate or polyphosphate-based pigment by reacting aluminum phosphate and sodium aluminate is provided. The amorphous aluminum phosphate or polyphosphate is characterized by a skeletal density of less than 2.50 grams per cubic centimeter and a phosphorus to aluminum mole ratio of greater than 1. In one embodiment, the composition is useful in paints as a substitute for titanium dioxide. CA2660564 (C); CA2660564 (A1) C01B25/36 C01B25/40 C08K3/32 C09C1/40 C09D5/00 C09D7/12 C09D11/00 C09D11/02
