Abstract
Abstract A process for providing a color image comprises exposing a radiation sensitive layer over a vapor deposited colorant layer and vaporizing the colorant to selectively transmit the colorant through the exposed layer. The change in solubility, penetrability and/or crosslinking or polymerization causes differential migration through the exposed layer.
