  • Patent number: 9856402
    Abstract: One or more cuts is provided in a label liner sheet near the area of a cutout within the label, such as the center hole in a CD label, in order to facilitate reliable separation of the cutout from the label and retention of the cutout on the liner sheet as the label is peeled from the liner. The majority of the cut runs generally parallel to the cutout boundary underneath the cutout, and the ends of the cut cross the boundary at two separate boundary crossing points on either side of the portion of the cut running parallel to the boundary. The cut first causes a flap to be created in the liner sheet and partially lifted as the label is beginning to be peeled away. Thereafter, as the peel line passes the flap area, the cutout experiences the full retentive strength of the label's pressure sensitive adhesive primarily at the two boundary crossings, and the cutout is pulled from the label and retained on the liner sheet as the adhesive force overcomes the cohesive force.

  • Patent number: 9823763
    Abstract: Provided is a touch panel. The touch panel includes a base and a pressure-sensitive adhesive layer attached to the base and having a peel strength with respect to a polycarbonate sheet of 1,900 g/25 mm or more. The pressure-sensitive adhesive layer includes an acryl polymer compound containing an acryl polymer and a thiol polymer derived by binding a thiol compound into a chain, or a side chain or terminal end of a chain of the acryl polymer. Accordingly, penetration of oxygen, moisture or other impurities at an interface between the base film and the pressure-sensitive adhesive layer, or at an interface between a conductor thin film and a pressure-sensitive adhesive layer may be effectively inhibited, and degradation in optical properties such as visibility due to bubbles generated at a pressure-sensitive adhesive interface may be prevented.
