Titanium dioxide has been used as a filler and coating pigment in the manufacture of paper products for many years. In addition to its ability to make papers whiter and brighter, it is a most important opacifying material.

Since brightness, whiteness, and opacity are very important properties of paper, this report deals with beater applications where the pigment serves to brighten and opacify the sheet with minimum loading or filling, coating applications, and the combination of both. The effectiveness of the titanium dioxide is investigated by testing the coated and the loaded hand sheets for brightness, opacity, and gloss.
