First claim

Opening claim text (preview).

The invention claimed is: 1. A 2-ply tissue paper, wherein a basis weight per ply is 15 to 18 g/m 2 , the 2-ply paper thickness is 135 to 160μm, and the 2-ply tissue paper contains 2.9 g/m 2 or more and 8.0 g/m 2 or less of chemical agents which contains glycerin and 1,3- propanediol, wherein glycerin and 1,3-propanediol weigh between 83.7 mass % or more and 94.9 or less mass % in a total amount of the chemical agents, wherein the blending ratio of 1,3-propanediol to glycerin is above 1: 0.04 and 1: 5.58 or less. 2. A 2-ply tissue paper, wherein a basis weight per ply is 16.2 g/m 2 or more and 17.4 g/m 2 or less, the 2-ply paper thickness is 136 pm or more and 156 pm or less, and the 2-ply tissue paper contains 2.9 g/m 2 or more and 8.0 g/m 2 or less of chemical agents which contain glycerin and 1,3- propanediol, wherein glycerin and 1,3-propanediol weigh between 83.7 mass % or more and 94.9 or less mass % in a total amount of the chemical agents, wherein the blending ratio of 1,3-propanediol to glycerin is above 1: 0.04 and 1: 5.58 or less. 3. The 2-ply tissue paper according to claim 1 , wherein the 2-ply dry tensile strength in the CD direction is 51 cN/25 mm or more and 62cN/25mm or less, the 2-ply wet tensile strength in the CD direction is 39 cN/25 mm or more and 58cN/25mm or less, and the ratio of the 2-ply wet tensile strength in the CD direction to the 2-ply dry tensile strength in the CD direction is 0.68 or more.
