The present invention provides a polymerizable inorganic particle dispersant that can achieve an inorganic-organic composite particle and inorganic-organic resin composite material, which have a high refractive index and a high Abbe's number, i.e., which can achieve both of a high refractive index and a high Abbe's number that is non-conventional in a composite with an inorganic particle. The present invention relates to a polymerizable inorganic particle dispersant comprising a compound which includes the following functional groups A, B and Q: A: Polymerizable functional group; B: Carboxyl group, Oxo acid group containing a phosphorous or Oxo acid group containing sulfur; and C: Sulfur-containing divalent or more aliphatic hydrocarbon group, which may contain a hetero atom other than sulfur.

Polymerizable inorganic-particle dispersant, inorganic-organic composite particles containing said polymerizable inorganic-particle dispersant, and inorganic-organic resin composite material

An object of the present invention is to provide an electrolyte for an electrolytic capacitor, which is advantageous not only in that both electric conductivity and withstand voltage property are high, but also in that thermal stability is excellent, and an electrolytic capacitor using the electrolyte. Specifically, the present invention provides an electrolyte for an electrolytic capacitor, comprising a solvent, at least one quaternary amidinium salt selected from the group consisting of a quaternary amidinium salt of a hydroxy-substituted aromatic monocarboxylic acid and a quaternary amidinium salt of phthalic acid, and metal oxide particles, and an electrolytic capacitor using the electrolyte.
