A pigment composition containing titanium dioxide (TiO2) and calcined clay in a weight ratio of between about 30:70 and 70:30, preferably between about 35:65 and 45:55 that is substantially free of a functional microgel component has advantages over a similar pigment containing a functional microgel. The pigment composition contains an amount of epichlorohydrin dimethylamine condensate that is sufficient to cationize the pigment, and lacks a microgel component. It is liquid when agitated. Preferably the composition has a solids content greater than about 55%, and most preferably between about 59% and about 61%. |
