Abstract
Abstract A laminate construction is provided which includes a backing sheet, a face sheet covering at least a portion of the backing sheet, and a releasable adhesive securing the face sheet to the backing sheet. The construction also includes first and second compositions which, when combined, form a distinctive color. The compositions are so arranged in the construction so that the application of an imaging force to the face sheet causes the compositions to combine and produce a color in the area beneath the imaging force. The face sheet can be peeled away to provide a nontacky label or the like, while a duplicate copy of the information printed onto the face sheet remains on the backing sheet. The construction may also include one or more intermediate plied which provide additional copies of the information.
