  • Patent number: 6500509
    Abstract: A pressure sensitive transfer tape such as transfer-type pressure sensitive correction tape or transfer-type pressure sensitive adhesive tape, for mounting in a handy-type transfer tool is provided, comprising a film support, which in turn comprises an organic polymer, and a pressure sensitive transfer layer on the film support, the pressure sensitive transfer layer comprising at least a pressure sensitive adhesive layer, the support having a first coefficient of kinetic friction on the transfer layer side of the support against a surface of a receiving object and a second coefficient of kinetic friction on the rear side of the support against a head member of a transfer tool, the first coefficient of kinetic friction being larger than the second coefficient of kinetic friction, and the difference between the first coefficient of kinetic friction and the second coefficient of kinetic friction being not less than 0.01.
