Abstract
Abstract An applique is attachable by pressure sensitive adhesive or the like to a supporting surface. The applique includes a base sheet, a layer of color changeable liquid crystalline material disposed upon the base sheet, and a transparent covering layer overlying the liquid crystalline layer. The applique is removable for use as a novelty or a premium item and is color changeable by application of heat, such as from the user's fingers, to the applique since such heat causes a color change in the liquid crystalline layer.
