Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
65 words
Electroconductive paper including a layer of a coating composition containing sodium chloride and a water-soluble polymer consisting of units derived from diallyl dimethyl ammonium chloride, wherein the electroconductive paper contains about 0.1 to 3.0 pounds of the coating composition per 3,000 square feet of the paper and the molar ratio of the sodium chloride to the dialkyl dimethyl ammonium chloride ranges from 1:3 to 3:1.
Claim 2
Dependent Claim
65 words
Electroconductive paper including a layer of a coating composition containing sodium chloride and a water-soluble polymer consisting of units derived from diallyl dimethyl ammonium chloride, wherein the electroconductive paper contains about 0.1 to 3.0 pounds of the coating composition per 3,000 square feet of the paper and the molar ratio of the sodium chloride to the dialkyl dimethyl ammonium chloride ranges from 1:3 to 3:1.
Claim 3
Dependent Claim
21 words
The electroconductive paper of claim 1 wherein the coating composition contains equimolar amounts of the water-soluble polymer and the sodium chloride.
