Abstract
An antireflective coating composition includes a photopolymerizable acrylate monomer (C1); a particle-type metal fluoride (C2) with a refractive index of 1.40 or less; a photopolymerization initiator (C3); and at least one liquid dispersion-enhancing chelating agent (C4) selected from the group consisting of Mg(CF3COO)2, Na(CF3COO), K(CF3COO), Ca(CF3COO)2, Mg(CF2COCHCOCF3)2 and Na(CF2COCHCOCF3). This composition ensures good mechanical strength, excellent adhesion to a substrate, short curing time by UV curing, prevention of dust attachment, good erasure of stain, good dust removal and good scratch resistance, so it is usefully for making an antireflective coating film of a display.
