Abstract

A pressure sensitive adhesive composition comprised of a substantially tacky polymer containing a number of prismatic or holographic platelets. When the composition is applied to a substrate, the platelets align themselves in a planar fashion parallel to the broad face of the surface on which the coating is applied. The resulting composition layer is transparent except for the platelets that refract and reflect the light striking the platelets back towards an observer. The color of the reflected light changes as the angle at which the platelets are viewed is changed. In this manner, the platelets in the coating provide an overall aesthetically pleasing appearance for the coated material that adds distinctiveness to decorative labeling, as well as to the objects on which the labeling is placed and other suitable types of laminations in which the adhesive coating may be used. Furthermore, the labeling may be used as an indication of counterfeit objects or of tampering with the object on which the labeling is placed because the platelets will either not be in an aligned position, or will shift from their aligned position within the adhesive composition when the labeling is disturbed.
