Patent ID: 7687127

Claim:
A label paper comprising: a polyolefin thermoplastic resin sheet (A) formed by stretching along at least one axis and heat treating at 50 to 250° C.; an adhesive layer (B); and a release paper (C), wherein the polyolefin thermoplastic resin sheet (A) has a Clark stiffness of from 15 to 500, wherein under a thermomechanical analysis with heating from a room temperature to 150° C., α is in a range of from −2.5 to 2.5 percent, and α-β is in a range of from −1.5 to 1.5 percent, where α is a ratio of a dimension of the polyolefin thermoplastic resin sheet (A) after the heating to a dimension of the polyolefin thermoplastic resin sheet (A) before the heating, and β is a ratio of a dimension of the release paper (C) after the heating to a dimension of the release paper (C) before the heating, and wherein the polyolefin thermoplastic resin sheet (A) comprises an electrostatic capacity modifier including at least one of vinylidene fluorides, polyester polyols, quaternary ammonium salts, rutile-type titanium oxides, barium titanate, treated calcium carbonates and carbon.
