PROCESS FOR PRODUCTION OF TITANIUM DIOXIDE PIGMENT AND RESINCOMPOSITIONS CONTAINING THE PIGMENT

摘要

A process for production of titanium dioxide pigment which comprises the ste p of dry-coating the surfaces of titanium dioxide pigment particles with hydrolyzates of an alkylsilane represented by the general formula (1): (1) [wherein R is alkyl having five or fewer carbon atoms; R~ is a hydrolyzable group; and n is 1 to 3 and m is 0 to 2, with the proviso that m and n satisf y the relationship: n + m <= 3.] The process can give titanium dioxide pigm ents excellent in hydrophobicity, dispersibility and heat resistance.
