RADIATION CURABLE RESIN COMPOSITION AND CURED FILM

摘要

To provide a radiation-curable resin composition exhibiting excellent curability and capable of forming a coating having high hardness, superior scratch resistance, low curling properties, superb adhesion, and excellent transparency, particularly high hardness and low curling properties, on the surface of a substrate, and a cured film of the composition. A radiation-curable resin composition comprising (A) particles produced by bonding oxide particles of at least one element selected from the group consisting of silicon, aluminum, zirconium, titanium, zinc, germanium, indium, tin, antimony, and cerium, with an organic compound including a polymerizable unsaturated group and a group shown by the following formula (1), (B) a compound containing two or more polymerizable unsaturated groups, (C) a surfactant containing a fluorine atom, and (D) an organic solvent containing one or more compounds selected from the group consisting of methanol, methyl isobutyl ketone, and n-butanol in an amount of 50 mass% or more in the total solvent. Formula (1) wherein U represents NH, O (oxygen atom), or S (sulfur atom), and V represents O or S.
