The process and products of this invention are illustrated further by the following examples, but the invention is not limited thereto or to their specific disclosures.EXAMPLE 1 One thousand (1,000) kg. of anatase TiO pigment is slurried with 5,000 liters of cold water in the presence of sufficient sodium silicate to raise the pH to 9 (use is made of about 15 to 25 liters of a solution containing 320 g,stone crushing business plan. per liter of solid and having a SiO /Na O ratio of about 3/ 1. This solution is well stirred and a solution of 5 kg. sodium stearate in 250 liters of water is added thereto over a period of 15 minutes. (The sodium stearate solution may be prepared at a boiling temperature, a slight turbidity may develop on cooling but has no effect on the final results.)

After minutes of continued stirring, a progressive addition is made of 130 kg. of hydrated aluminum sulfate (Al (SO .18H O) dissolved in 400 liters of water. Stirring is continued for 30 minutes and then the pH is adjusted to 7 by addition of caustic soda, followed by separating the water by filtering or other appropriate means, and by washing the coated pigment and drying at 120 C. The disintegrated product eventually obtained is a white powder which is easily wetted by organic solvents such as benzene.

EXAMPLE 2 One thousand (1,000) kg. of a rutile TiO' pigment (hydroclassified to a maximum particle size of 2 microns) is suspended in 5,000 liters of water in the presence of 20 liters of a sodium silicate solution having a composition identical to that used in Example 1. To the thoroughly mixed slurry, an aqueous solution of 5 kg. sodium abietate is added. After 10 minutes continuous stirring an addition is made of 130 kg. of hydrated aluminum sulfate (Al (SO -18H O) dissolved in 400 liters of water. Stirring is continued for 30 minutes and then the suspension is neutralized by means of caustic soda.After filtering, washing, drying at C. and disintegrating; a pigment is obtained...
