Heat activating and thermosensitive recording for thermosensitive adhesive label

摘要

There is provided an apparatus for heat-activating a thermosensitive adhesive label. The thermosensitive label includes a support and a thermosensitive adhesive agent layer provided thereon which is not adhesive at room temperature, but becomes adhesive with application of heat. The apparatus according to the present invention includes a heating medium and a platen roller arranged opposite to the heating medium. The thermosensitive adhesive label is transported between the heating medium and the platen roller in a direction where the thermosensitive adhesive agent layer is faced with the heating medium. When a friction coefficient between the thermosensitive adhesive agent layers is less than 2.0, a pressing force of the thermosensitive adhesive label between the heating medium and the platen roller is in a range of from 50 to 5,000 g/25 mm at room temperature.
