Abstract
A temperature-responsive adhesive article comprises (a) a temperature-responsive carrier capable of changing its shape at a first transition temperature; and (b) a thermomorphic pressure-sensitive adhesive on at least a portion of at least one surface of the carrier, the thermomorphic pressure-sensitive adhesive being capable of changing its shape at a second transition temperature. By varying the initial shapes or topographies of carrier and adhesive and the relationship between the transition temperatures, the article of the invention can be designed to provide a wide variety of bonding and de-bonding properties.
