Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
75 words
A multi-color image laminate comprising a substrate having a coating of appreciable thickness of a polymer having carbon-to-carbon double bond unsaturation, said polymer containing some portions which have been hydroperoxidized by imagewise exposure to light in the presence of oxygen, and other portions that have not been subjected to said exposure, wherein either the exposed or non-exposed portions contain coloring materials at different levels of the laminate to present a multi-color image to the viewer.
