1. A process for providing a color image from an imageable article comprising a substrate, a vapor-deposited dye or pigment, and a radiation sensitive layer said process comprising:
- (a) exposing said radiation sensitive layer to an imagewise distribution of radiation which alters the solubility and/or permeability of said layer, and(b) heating said imageable article uniformly to evaporate said dye or pigment at different rates from the article to provide an imagewherein a receptor is in contact with said article and evaporated dye or pigment deposits on a surface of said receptor to form an image, andwherein said photoresist layer is an organic negative-acting photoresist layer and said heating is performed without etching of the photoresist layer.

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.
