Claims14
A solid particulate rutile TiO.sub.2 pigment substrate having a coating consisting essentially of (a) a polymeric amine metallate of the general formula ##STR6## where R is an alkylene radical of from 2-6 carbon atoms, n is an integer of 4-6, q is 1 when M is aluminum and q is 3/2 when M is zinc and M is aluminum or zinc or (b) a polymeric amine metallate of the general formula ##STR7## where p is an integer from 2-5, n is an integer of 4-6, R is as defined above and the amount of aluminum or zinc expressed as an oxide is 0.17-2% by weight based on the weight of substrate.
