PURPOSE:To obtain an inorganic powder such as magnetic or metal one, provided with organic nature with the surface hydrophobicized, by modifying the surface with a specific organophosphorus compound treatment. CONSTITUTION:The objective inorganic powder surface-modified with an treatment consisting of an organophosphorus compound of formula [R and R' are each (substituted) 1-30C alkyl, alkenyl, aryl, alkoxy, alkenoxy, or aryloxy], e.g., dibutyl phosphate. For said R or R', 4-18C alkyl will be preferable, if alkenyl or mercapto is selected, improved mechanical properties of the resin filled with said powder will also result. Enhanced fluidity and dispersibility in the processing of the above composite resin will lead, for example, to the viscosity drop in a polyvinyl chloride paste, improved impact resistance of the resin composition, etc.
