摘要： An antiglare-treated article comprising an acrylic resin substrate and a fluorine-containing polymer coating formed on the surface of the substrate, wherein the thickness of the coating is in the range between 0.03 and 0.5 &mgr;m, and the fluorine-containing polymer has a refractive index in the range between 1.30 and 1.40 and comprises a block which is compatible with the acrylic resin and a block comprising a fluorine-containing elastomer. This treated article can be stably produced at low costs although it has the same abrasion resistance and antiglare effects as those of conventional antiglare-treated articles, or it has better antiglare effects than conventional antiglare films while maintaining abrasion resistance.
