Description

上記感圧転写テープや感圧転写粘着テープ、感圧粘着テープ等の感圧テープは、長尺の帯状に形成したものを、ロール状に巻回した状態で供給されるのが一般的である。そして、感圧テープには、感圧粘着層が基材の背面に接着したり粘着したりする、いわゆるブロッキングが生じるのを防止しつつ、高い粘着力を有することが求められる。
特に、感圧転写テープや感圧転写粘着テープは、例えばホルダに装着して、当該ホルダを紙等の上で移動させた際に、感圧粘着層の粘着力によってテープを繰り出すと共に、感圧転写テープの場合は着色層を基材から離型させ、また感圧転写粘着テープの場合は感圧粘着層を基材からはく離させつつ、ホルダに設けたヘッドによって紙等の表面に圧着させることで、当該表面に粘着させることが行われるが、その際にブロッキングが発生すると、感圧粘着層が、基材の背面に粘着してテープをスムースに繰り出しできない走行不良を生じるおそれがある。また、感圧転写テープの場合は感圧粘着層と着色層とが基材の背面に付着し、感圧転写粘着テープの場合は感圧粘着層が基材の背面に付着した後、上記ヘッド等に転移して、転写時に、カスとして紙等の表面に付着してしまうおそれもある。 Pressure-sensitive tapes such as the above-mentioned pressure-sensitive transfer tape, pressure-sensitive transfer adhesive tape, and pressure-sensitive adhesive tape are generally supplied in a state of being formed into a long strip and wound into a roll. . The pressure-sensitive tape is required to have a high adhesive force while preventing the so-called blocking that the pressure-sensitive adhesive layer adheres to or adheres to the back surface of the substrate.
In particular, when a pressure-sensitive transfer tape or pressure-sensitive transfer adhesive tape is mounted on, for example, a holder and the holder is moved on paper or the like, the tape is fed out by the adhesive force of the pressure-sensitive adhesive layer, and pressure sensitive. In the case of a transfer tape, the colored layer is released from the substrate. In the case of a pressure-sensitive transfer adhesive tape, the pressure-sensitive adhesive layer is peeled off from the substrate, and the head is attached to the surface of paper or the like by a head provided on the holder. In this case, if blocking occurs , the pressure-sensitive adhesive layer may adhere to the back surface of the base material, resulting in a running failure in which the tape cannot be smoothly fed out. In the case of a pressure-sensitive transfer tape, the pressure-sensitive adhesive layer and the colored layer are attached to the back surface of the substrate, and in the case of the pressure-sensitive transfer adhesive tape, the pressure-sensitive adhesive layer is attached to the back surface of the substrate, and then the head May be transferred to the surface of paper or the like during transfer.
