Provided are an insulated ultrafine powder obtained by adding liquid metal alkoxide to a methanol-containing organic solvent in which a conductive ultrafine powder comprising a carbon material is dispersed and further adding water thereto and a method for producing the same. Also, provided are an insulated ultrafine powder obtained by adding liquid metal alkoxide to a methanol-containing organic solvent in which a conductive ultrafine powder comprising a carbon material is dispersed, further adding a coupling agent having an alkoxide group and then adding water thereto and a method for producing the same. Further, provided is a high dielectric constant resin composite material obtained by blending the insulated ultrafine powder of the present invention with a resin in a volume ratio (insulated ultrafine powder/resin) falling in a range of 5/95 to 50/50.

An object of the present invention is to improve the compatibility of the resin composition comprising the PAI resin and the PAS resin so as to provide a resin composition which is excellent in flowability when molten, strength, tenacity and heat resistance. A resin composition comprising:

Resin composition

A resin composition comprising a melt-kneaded product of (A) an aromatic polyamideimide resin (Component A) which is obtained by polymerizing an aromatic tricarboxylic acid anhydride and a diisocyanate in a solvent under conditions where an amide group is substantially formed first and then an imide group is formed, and which has at least one recurring unit of the formula (1), ##STR1## wherein Ar is a trivalent aromatic hydrocarbon group having at least one 6-membered carbon ring, and R is a divalent aromatic hydrocarbon group or an aliphatic hydrocarbon group, and (B) a polyphenylene sulfide resin (Component B); and the molded article obtained by molding said resin composition.
