<P>PROBLEM TO BE SOLVED: To provide a Braille tile which can be strongly stuck to a laying surface with excellent dimension stability by construction work in a short time without the need of complicated work such as using a mold form. <P>SOLUTION: The Braille tile comprises a resin sheet with a plurality of projections on the upper surface obtained by curing a curable mixture whose main constituent is an acrylic monomer which is acrylic syrup containing a polymer component and a polyfunctional monomer selected from at least acrylic monomer, divinylbenzene, triallyl isocyanurate, triallyl cyanurate, allyl methacrylate, ethylene glycol di(meth)acrylate, diethylene glycol di(meth)acrylate, triethylene glycol di(meth)acrylate, polyethylene glycol di(meth)acrylate, polypropylene glycol di(meth)acrylate, 1, 3-butylene glycol di(meth)acrylate, 1, 6-hexanediol di(meth)acrylate, neopentyl glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, tetramethylolmethane tri(meth)acrylate and tetramethylolmethane tetra(meth)acrylate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
