  "abstract": "The invention relates to a hardening resin composition including a monomer represented by the formulas (1) or (2), a monomer represented by the formula (3), and epoxyacrylate or epoxymethacrylate. This composition is easily hardened at low temperature, weak in odor, small in shrinkage in hardening, excellent during durability against water and hot water, and thus suitable as the flooring material for a food processing factory, refrigerated warehouse, and cold storage. (1) (2) (3) where R1 to R6, p and r are as defined.",
  "claims": [
    "1. A hardening resin composition consisting essentially of at least one monomer selected from an acrylic monomer and a methacrylic monomer represented by formulas (1) and (2), which is in the range of 60 to 90% by weight of the total monomer content, at least one monomer selected from bifunctional acrylic monomer and bifunctional methacrylic monomer represented by formula (3), which is in the range of 5 to 20% by weight of the total monomer content, and at least one monomer selected from epoxyacrylate and epoxymethacrylate, which is in the range of 5 to 20% by weight of the total monomer content, ##STR13## wherein R 1 is hydrogen or methyl, R 2 is ethylene or trimethylene, and p is an integer of 0 to 5; ##STR14## wherein R 3, R 5 and R 6 are the same or different and are hydrogen or methyl, R 4 is ethylene or trimethylene, and r is an integer of 1 to 10.",
    "2. A hardening resin composition as set forth in claim 1, wherein said epoxyacrylate is at least one selected from the group consisting of acrylate of tris-phenolmethane epoxy resin, acrylate of phenolnovolak epoxy resin, and acrylate of bifunctional bisphenol epoxy resin, and said epoxymethacrylate is at least one selected from the group consisting of methacrylate of tris-phenolmethane epoxy resin, methacrylate of phenolnovolak epoxy resin, and methacrylate of bifunctional bisphenol epoxy resin.",
    "3. A hardening resin composition as set forth in claim 2, wherein the acrylate or methacrylate of said bisphenol epoxy resin is represented by formula (4): ##STR15## wherein R 7 is hydrogen or methyl, and s is an integer of 1 to 10.",
    "4. A hardening resin composition as set forth in claim 1, further comprising an organic peroxide as a hardening agent.",
    "5. A hardening resin composition as set forth in claim 1, wherein organic metal salt, is contained as a hardening promoter.",
    "6. The hardening resin composition of claim 5 wherein said organic metal salt is at least one member selected from the group consisting of organic metal complexes and aromatic amines.",
    "7. A hardening resin composition as set forth in claim 1, further comprising a filler included."
