Title: REVEAL SUBSTRATE AND METHODS OF USING THE SAME
Abstract:
Disclosed is a reveal substrate comprising: a) a top substrate layer comprising an opaque polymer sensitive to application of heat or pressure, and becoming transparent upon being heated to a predetermined temperature or subjected to a predetermined pressure, and b) a bottom substrate layer having one or more colored areas on a top surface thereof, disposed such that said one or more colored areas are obscured by the opaque polymer prior to being heated to the predetermined temperature or subjected to the predetermined pressure, and are revealed subsequent thereto, wherein: each of the one or more colored areas comprises at least two different colors, and comprises a two-dimensional matrix formed by a plurality of color blocks, each one of the plurality of color blocks having only one color, and the color blocks are arranged to have a repeating color pattern. Alternatively the top substrate layer comprises an opaque material which can be induced by, e.g., UV, to become transparent. Further the top substrate layer can comprise a transparent material which can be induced by, e.g., UV, to become opaque. Methods of using the disclosed substrates are also disclosed.
