To improve antifouling property, fireproofness and wear resistance by coating a hard coating layer with a hard coating film containing a surface treating silica, an acrylate and a photopolymerization initiator.
The decorative plate is coated with a hard coating layer containing a surface treating silica, an acrylate and a photopolymerization initiator. The acrylate contains a diacrylate and a triacrylate, or contains the triacrylate a tetraacrylate and/or a pentaacrylate. As the diacrylate, a 1,6- hexanediol diacrylate is used, as the triacrylate, a trimethylolpropane triacrylate is used, as the tetraacrylate, a dihexaerithritol tetraacrylate is used, as the pentaccrylate, a dipenta-erithritolmonohydroxy pentaacrylate is used, and at least two types are used. The agent contains a surface treating silica, an ascrylatemonomer or an oligomer, arbitrarily an additive such as a leveling agent, and a photopolymerization initiator.
