Dipentaerythritol pentaacrylate → 1-Hydroxycyclohexyl phenyl ketone

Participants

Reaction Steps

To 10.0 parts by mass of a hard coating agent containing ZrO2 fine particles (DeSolite Z7404 produced by JSR Corp. [refractive index: 1.72, solids concentration: 60 mass %, particulate zirconium oxide content: 70 mass % (with respect to the solids content), average size of particulate zirconium oxide: around 20 nm, solvent composition: MIBK/MEK=9/1]), 3.0 parts by mass of a mixture of dipentaerythritol pentaacrylate and dipentaerythritol hexaacrylate mixture (DPHA), 0.1 parts by mass of a photopolymerization initiator (Irgacure 184, produced by Ciba Specialty Chemicals) and 86.9 parts by mass of methyl isobutyl ketone were added, and these ingredients were thoroughly stirred. Then the mixture obtained was passed through a polypropylene filter having a pore size of 0.4 μm. Thus, a coating solution for a medium refractive-index layer (MNL-1) was prepared.
