Abstract
An image receptive film comprising a surface layer containing a photosensitive polyacetylenic compound having at least two acetylenic linkages in a conjugated system is subjected to a plurality of radiant energy exposures each limited to a divisible portion of the image to be transmitted and at least each of 2 exposures effected at a distinctive dosage level, to develop exposed discrete portions in its respective divided portion to a characteristic color distinguishable from that developed in the surface layer by any other exposure at a different dosage level.
Claims16
The process of subjecting an image receptive film having a surface layer of a photosensitive polyacetylenic compound to a plurality of separate radiant energy exposures at distinctive dosage intensity levels the exposure at higher intensity being effected with a particulate source of irradiation, each exposure at said distinctive dosage intensity level being limited to a divisible portion of the overall image to be transmitted, so as to develop exposed discrete portions of the image in the corresponding divided portion po a color distinguishable from the color of any other exposed portion resulting from another exposure at a dissimilar dosage intensity level in said surface layer.
