Methyl Ethyl Ketone → Pentaerythritol

Participants

Reaction Steps

Diluted with a mixed solvent including butyl acetate and methyl ethyl ketone at a weight ratio of 1 to 2 were 100 parts of urethane acrylate obtained from pentaerythritol-based acrylate and hydrogenated xylene diisocyanate as urethane acrylate (A), 20 parts of isocyanuric acid-tris[2-(acryloyloxy)ethyl] as isocyanuric acid acrylate (B), silica ultrafine particles with an average particle diameter in the range of from 10 to 20 nm as inorganic ultrafine particles (C) in a content of 40% relative to all the solid matter and a polymerization initiator (with a trade name of IRUGACURE 184, manufactured by Ciba Specialty Chemicals Inc.) in a content of 3% relative to all the solid matter, so as to obtain a solution with a solid matter concentration of 45% to thereby prepare a hard coat forming material (in the state of a solution).
