Abstract
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.
