<p>[PROBLEMS] To provide an organosol of a surface-modified fluoride colloid particle, which is produced by coating the surface of a core comprising a fluoride colloid particle with an organophosphorus compound, and also provide a method for producing the organosol. [MEANS FOR SOLVING PROBLEMS] An organosol of a surface-modified fluoride colloid particle, which is produced by coating the surface of a core comprising a fluoride colloid particle with at least one organophosphorus compound selected from the group consisting of organophosphorus compounds represented by the general formulae (1), (2) and (3). (R-O)nP(=O)(OM)3-n (1) (R-O)nP(OM)3-n (2) (R)nP(=O)(OM)3-n (3) wherein R represents a substituted or unsubstituted alkyl, alkenyl or aryl group; M represents a hydrogen atom, an alkali metal or NZ4 (wherein Z represents a hydrogen atom or an alkyl group); and n represents an integer of 1 or 2.</p> |
