Abstract:
1. A multi-layered laminate media on which information may be applied in machine or human readable form on a visible front surface of said media by the output of a high intensity light source, comprising: a media substrate, said substrate having back and front surfaces, a light absorbent layer, said layer adapted to absorb light from said output of said high intensity light source and to convert said absorbed light into heat, a thermochromic layer in thermal contact with said light absorbent layer, said thermochromic layer forming said visible, front surface of said media, wherein portions of said thermochromic layer change visual appearance in response to application of said output of said high intensity light source into said light absorbent layer, and conduction of heat converted from light absorbed by said light absorbing layer into said thermochromic layer, and obscuration means between said light absorbent layer and said visible, front surface of said thermochromic layer which reduces the visibility of said light absorbent layer to the naked eye, wherein said obscuration means comprises a variable obscuration layer which becomes opaque in selected portions as it absorbs heat.
