CURABLE RESIN COMPOSITION FOR BRAILLE TILE, AND CURED PRODUCT THEREOF AND BRAILLE TILE
PROBLEM TO BE SOLVED: To provide a curable resin composition for braille tile that is suitable for molding in viscosity and gelation time, and has low hardness, and excellent strength and elongation.SOLUTION: A curable resin composition for braille tile has a (meth) acrylic polymer (A) comprising a methyl methacrylate (a-1) unit: 5-95 mass%, an alkyl (meth) acrylate (a-2) unit of an alkyl group with 2-20 carbon atoms: 5-95 mass%, and a radical-polymerizable monomer (a-3) unit other than (a-1) and (a-2): 0-20 mass%, methyl methacrylate (B), alkyl (meth) acrylate (C) with 2-20 carbon atoms, polyfunctional (meth) acrylate (D), reductant (E) and curing agent (F). There are also provided a cured product made by curing the curable resin composition for braille tile, and a braille tile comprising the cured product.SELECTED DRAWING: None
