<P>PROBLEM TO BE SOLVED: To provide an adhesive label which is non-adhesive at preservation but exhibits full adhesiveness when it is used. <P>SOLUTION: The adhesive label is characterized by that at least an adhesive material layer is provided on a base material and a resin film layer is provided on the adhesive material layer. The thickness of the resin film layer is ≤10 μm, and a polyester film is preferable as a resin film. Also, it is preferable that the resin film be composed of a biaxially oriented polyester film, the thickness (d) is in the range of 1 to 3 μm and the surface satisfies Formula (1) and Formula (2). After a hole is made on the resin film layer by a heating or physical method to make the adhesiveness appear, the label is stuck to a body to be attached. The Formulas are SRma/d≤0.7 (1) and SSr≥30 (2), where SRma indicates a three-dimensional surface maximum height [μm], (d) indicates a film thickness [μm] and SSr indicates the center surface area ratio [%]. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
