PURPOSE:To provide stable treated powder suitable for colorants used for coatings, etc., magnetic materials, etc., in an improved reaction rate and selectivity, by adding water to a reaction solvent in an addition reaction of a vinylic compound with powder coated with a specific silicon compound. CONSTITUTION:The objective powder is produced by adding water to a reaction solvent in an addition reaction of a vinylic compound (an unsaturated compound, having >= one C=C and CidenticalC bonds and reactive with a Si-H group) with powder coated with a silicon compound having the Si-H group. |
