DISPERSION OF INORGANIC PARTICLE, ENERGY-RAY CURABLE RESIN COMPOSITION, AND FILM

摘要

The invention provides an inorganic particle dispersoid, an energy ray-curable resin composition and a film. The dispersoid of a cured product has high hardness and dispersion stability and is characterized in that the dispersoid is obtained by dispersing inorganic particles A for surface treatment into reactive dispersant. The inorganic particles A for surface treatment are obtained by treating surfaces of inorganic particles b1 with a compound B containing (methyl) acryloyl. The reactive dispersant is a reaction product generated during an additive reaction between monomers containing (methyl) acryloyl and carboxyl and (methyl) acrylic polymers containing epoxy radical; or a reaction product generated during an additive reaction between monomers containing (methyl) acryloyl and epoxy radical and acrylic polymers containing carboxyl (methyl) acrylic; wherein the content of the (methyl) acryloyl is 200-600, and the hydroxyl value is 90-280mg/KOH.
