Abstract
A pressure-sensitive adhesive transfer tape that may have on one surface of a release substrate made of paper or a plastic film, a pressure-sensitive transfer layer having an adhesion inhibiting layer and an adhesive layer, wherein the adhesion inhibiting layer and the adhesive layer are successively stacked on one another. The adhesion inhibiting layer may prevent the adhesive layer formed on one adherend from being in contact with another adherend to weaken the adhesion between the one and another adherends, enabling the one and another adherends to be easily separated from each other. With the passage of time after being put on one another, the adhesion inhibiting layer may migrate to another adherend, so that the adherend is in contact with the adhesive layer, exhibiting strong adhesion properties between the adherends.
