Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 191 words
A non-slip article comprising a polymeric backing of material selected from the group consisting of polyvinyl chloride, polyethylene, polyurethane, polyester, polypropylene, polyamide, polysulfide, polystyrene, polyvinyl acetate, polybutadiene, styrene-butadiene, acrylonitrile-butadiene, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer and vinylidene chloride, said polymeric backing having from about 10 to 25 lbs./ream of a mineral particulate material bonded thereto by from about 4 to about 15 lbs./ream of radiation cured polyurethane binder material, said polyurethane binder material comprising a blended mixture of at least one grade of polyester urethane acrylate resin and a combination of ethoxyethoxyethyl acrylate and N-vinyl-2-pyrrolidone monomer, and wherein the linear tensile strength of the non-slip article is at least as great as the linear tensile strength of said polymeric backing, and wherein the elongation capability (before tearing occurs), of said non-slip article, is at least 25%, of that of said polymeric backing, and said elongation capability (before tearing occurs) of said non-slip article is also at least 125%, in any given direction, of the unelongated dimension in that same direction; the backer material and the resin bonding material being selected such that the non-slip is thermoformable without delamiantion or decomposition of the components.
Claim 2
Dependent Claim 191 words
A non-slip article comprising a polymeric backing of material selected from the group consisting of polyvinyl chloride, polyethylene, polyurethane, polyester, polypropylene, polyamide, polysulfide, polystyrene, polyvinyl acetate, polybutadiene, styrene-butadiene, acrylonitrile-butadiene, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer and vinylidene chloride, said polymeric backing having from about 10 to 25 lbs./ream of a mineral particulate material bonded thereto by from about 4 to about 15 lbs./ream of radiation cured polyurethane binder material, said polyurethane binder material comprising a blended mixture of at least one grade of polyester urethane acrylate resin and a combination of ethoxyethoxyethyl acrylate and N-vinyl-2-pyrrolidone monomer, and wherein the linear tensile strength of the non-slip article is at least as great as the linear tensile strength of said polymeric backing, and wherein the elongation capability (before tearing occurs), of said non-slip article, is at least 25%, of that of said polymeric backing, and said elongation capability (before tearing occurs) of said non-slip article is also at least 125%, in any given direction, of the unelongated dimension in that same direction; the backer material and the resin bonding material being selected such that the non-slip is thermoformable without delamiantion or decomposition of the components.
Claim 3
Dependent Claim 45 words
The article of claim 1 wherein said elongation capability (before tearing occurs) is at least 30% of that of said polymeric backing, and said elongation capability (before tearing occurs) is at least 140% in any given direction, of the unelongated dimension in that same direction.
Claim 4
Dependent Claim 45 words
The article of claim 1 wherein said elongation capability (before tearing occurs) is at least 40% of that of said polymeric backing, and said elongation capability (before tearing occurs) is at least 150%, in any given direction of the unelongated dimension in that same direction.
Claim 5
Dependent Claim 19 words
The article of claim 1 which comprises from about 15 to about 25 lbs./ream of said mineral particulate material.
Claim 6
Dependent Claim 20 words
The article of claim 1 which comprises from about 8 to about 12 lbs./ream of radiation cured polyurethane binder material.
Claim 7
Dependent Claim 18 words
The article of claim 1 wherein said radiation cured polyurethane binder material is electron beam cured binder material.
Claim 8
Dependent Claim 27 words
The article of claim 1 wherein said polymeric backing of material is selected from the group consisting of polyvinyl chloride, polyurethane, polyethylene, polyester, polyamide, polypropylene and polysulfide.
Claim 9
Dependent Claim 14 words
The article of claim 1 wherein said polymeric backing of material is polyvinyl chloride.
