PROBLEM TO BE SOLVED: To provide a dispersion, whose cured product has high hardness and which is excellent in dispersion stability, and furthermore to provide a method for producing the dispersion with the characteristics.SOLUTION: The dispersion includes a surface-treated inorganic particle (A), and a reactive dispersant in which the inorganic particle (A) is dispersed, wherein (1) the surface-treated inorganic particle (A) is a product obtained by surface-treating an inorganic particle (b1) with a (meth)acryloyl group-containing compound (B), (2) the reactive dispersant is a reaction product obtained by performing addition-reaction of an epoxy group-containing (meth)acrylic polymer with a (meth)acryloyl group and carboxyl group-containing monomer; or a reaction product obtained by performing addition-reaction of a carboxyl group-containing (meth)acrylic polymer with a (meth)acryloyl group and epoxy group-containing monomer; and has a (meth)acryloyl equivalent of 200-600, and a hydroxyl value of 90-280 mg/KOH. |
