ABSTRACT:
By treating metal oxide fine particles having a specific surface area of 5 to 500 m.sup.2 /g with a silane coupling agent and then further treating the fine particles with a reactive group-terminated organopolysiloxane, the organopolysiloxane is stably bonded to the surface of the powder particles, to thereby improve stability of the modifying effect against the elapse of time and durability.
