To provide a photopolymerizable dental coating composition that, when applied to the surface of a dental resin material such as crown restoratives, dental fillers, and denture or denture base resins, is thoroughly cured upon irradiation with a visible light and produces a smooth, colorless and transparent cured surface after curing so that a film having superior durability, abrasion resistance and resistance to discoloration can be formed, the photopolymerizable dental coating composition includes a volatile (meth)acrylate compound, a polyfunctional acrylate as a cross-linking agent, a fluoroalkyl group constituted of at least one fluorocarbon-containing (meth)acrylate compound for improving the durability, abrasion resistance and resistance to discoloration after curing, and an acyl phosphine oxide-based polymerization initiator having a high polymerization promoting effect for monomers, which does not make the polymerized composition remain yellowish. |
