<p>PROBLEM TO BE SOLVED: To provide a resin composition that can be used to inexpensively form a coating film in a half-cured state achieving both of blocking resistance and coating film elongation and that gives a coating film, after completely cured with active energy rays, imparting excellent scratch resistance and hardness to a surface of a molded article and having high transparency.SOLUTION: The resin composition comprises hydrophobic silica fine particles (A), a polyfunctional (meth)acrylate (B) having a weight average molecular weight of 10,000 to 200,000, and a photopolymerization initiator (C). A solution prepared by mixing the hydrophobic silica fine particles (A) with methyl isobutyl ketone, methyl ethyl ketone and normal hexane in a compounding ratio by weight of (silica fine particles (A)):(methyl isobutyl ketone):(methyl ethyl ketone):(n-hexane)=1:3:6:10, the solution shows a total ray transmittance of 60 to 99%.</p> |
