摘要： An ink composition comprising a microparticulate fluorescent material which can emit a high brightness fluorescent light by ultraviolet ray and has a predetermined nanosize is provided. The ink composition comprises a microparticulate fluorescent material represented by the formula YVO4:A, wherein A is a rare earth metal other than yttrium, which can emit a fluorescent light by the excitation with ultraviolet ray. The fluorescent material has an average primary particle size of 30 to 400 nm and has not been calcined. The fluorescent material is prepared by, for example, mixing Composition (I) containing a yttrium compound, a compound of rare earth metal other than yttrium and a complex forming compound in water with Composition (II) containing a vanadium compound in water and then reacting them.
