<p>A technical problem of this invention is to create in-mold labels that can be adhered to wide areas, including 3D curved areas, of the peripheral wall of a synthetic resin container in a high-grade state without air entrapment and/or wrinkling. A principal means of this invention to solve the technical problem described above is in-mold labels used as an inserted material and adhered to the outer peripheral wall of a container main-body concurrently when the main body is being molded, said labels comprising an adhesive layer to be adhered to the outer peripheral wall of the container main-body, wherein this adhesive layer has depressed portions on a back surface thereof, the depressed portions being formed by embossing and being disposed in a regular pattern, wherein the depressed portions has an average depth in a range of 0.02 to 0.1 mm, an average number in a range of 25 to 2,500 per square cm of a unit surface area of a label;, and a total of spatial volumes in a range of 0.001 to 0.005 cubic cm per square cm of the unit surface area of the label.</p> |
