Abstract
A laminate and a method for making a laminate having a hidden or shielded image. The laminate includes a substrate having an first surface containing an image thereon and a polymeric film laminated to the first substrate surface overlying the image. The film contains an exposed water activatable opaque layer having a thickness ranging from about 0.60 mil to about 2.0 mil, the opaque layer including aluminum silicate and a binder. Upon wetting the opaque layer, the hidden or shielded image is revealed. The method includes a means for producing the laminate in high volumes for minimizing the production costs thereof. Upon drying the opaque layer, the image is again hidden or shielded from view. The laminate may be used multiple times without adversely affecting its ability to reveal and hide images.
