ABSTRACT:
Positive-working imageable elements are prepared by providing a first layer and second layers onto a substrate. Both layers include the same or different radiation absorbing compounds dispersed within different polymeric binders. After both layers are dried, they are heat treated at from about 40 to about 90° C. for at least 4 hours under conditions that inhibit the removal of moisture from the dried first and second layers. This method of preparation provides elements with improved imaging speed and good shelf life.
