Abstract
A laminate including a plurality of layers, wherein one of the layers is a heat-activatable expandable layer including a thermally expandable composition. The heat-activatable expandable layer includes a plurality of microcapsules containing the thermally expandable composition. This thermally expandable composition includes an easily volatilizable hydrocarbon, and a binder resin. When subjected to high temperatures during the process of applying a label, the microcapsules rupture and the thermally expandable composition “foams,” which can be used to provide a texture to the label, and can raise or surround the graphics of the label.
