Abstract
A label paper including a 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). 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 thermoplastic resin sheet (A) after the heating to a dimension of the 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.
